Feature Proposal: Vibepollo MultiSeat — A High-Performance, Open-Source DuoStream Alternative

[Dani6ca-T]

Hi Nonary,

First of all, thank you for your incredible work on Vibepollo/Vibeshine. The integration of WGC in service mode, automated display handling, and built-in virtual drivers has completely redefined the self-hosted streaming ecosystem.

I want to propose a major architectural evolution for the project: transforming Vibepollo into a native, high-performance multi-session engine — Vibepollo MultiSeat.

The Philosophy: Giving a Second Life to Old Hardware
The core vision behind Vibepollo MultiSeat is to bridge a massive gap in home networking: sustainability and cost-efficiency. Instead of throwing away older laptops, cheap TV boxes, old tablets, or low-spec mobile devices, users can repurpose them into high-end gaming stations. By utilizing a single powerful host PC to stream independent, isolated game instances to multiple concurrent family members via Moonlight, we completely eliminate the need to buy multiple expensive gaming rigs or waste massive hardware overhead on heavy VM virtualization (like Hyper-V/GPU-P).

DuoStream proved that the global demand for multi-session streaming is massive, but its development has slowed down, and it severely struggles with controller conflicts, audio routing, and Windows Update stability. Vibepollo already does the heavy lifting regarding display virtualization and outstanding WGC capture. By adding a native session orchestration layer, this project can easily conquer the multi-seat ecosystem and become the ultimate eco-friendly home gaming hub.

To implement this without clunky third-party audio mixers (like VoiceMeeter) or unstable scripts, here is the core architectural blueprint for Vibepollo MultiSeat:

1. Dynamic Audio Provisioning via Windows DevCon API
   Instead of forcing users to install donationware virtual cables or VoiceMeeter, the Vibepollo background service can leverage the Microsoft DevCon (Device Console) utility. When a new streaming seat is deployed, the backend dynamically installs an independent, isolated virtual audio driver node (Root\MultiSeatAudio_SeatX). It then programmatically binds this device as the exclusive audio endpoint for that specific Windows Session ID, achieving 100% scriptable, zero-CPU audio isolation.

2. Version-Independent Session Unlocker (Pattern Scanning)
   To enable concurrent local sessions on Windows Pro/Home without RDPWrap-like memory offsets that break on every monthly Windows Cumulative Update, implement a SuperRDP-style runtime pattern scanning engine. It dynamically bypasses termsrv.dll restrictions in RAM. Additionally, suppressing standard RDP graphics pipes via registry forces Windows to route rendering strictly through the physical GPU and Vibepollo’s custom virtual displays from millisecond zero.

3. Dynamic Child-Process CPU Affinity Enforcement
   Standard multi-session environments fail when game launchers (Steam/Epic) spawn game processes that bypass initial core limits, starving the host. The MultiSeat module should deploy a proactive process watcher via WMI events (__InstanceCreationEvent) to dynamically catch and apply specific processor affinity masks to any newly spawned sub-process within that specific SessionId.

4. Advanced Virtual Network Interface (NIC) Isolation
   To prevent port collisions (e.g., port 27015) and account conflicts when multiple seats run the exact same game simultaneously, the orchestrator should automate the provisioning of Microsoft KM-TEST Loopback or Wintun/TAP adapters. By allocating distinct virtual IPs to separate sessions and using ForceBindIP64 routines within the launcher, outbound sockets are cleanly separated.

5. Windows Service-Level Session Overrides
   UAC Handling: Utilize CreateProcessAsUser combined with session tokens to inject a companion UI agent into the Winlogon desktop context of the secondary session, preventing stream freezes (black screens) during administrative prompts.

Power Management: Call the Win32 Power Management API (SetThreadExecutionState) to block Windows idle timers from putting the host machine to sleep while secondary seat users are actively streaming.

Clipboard Isolation: Enforce strict data isolation between concurrent family members by explicitly suppressing cross-session clipboard sharing via registry (fDisableClip = 1).

Interrupt Balancing (DPC Latency): Programmatically append core masks (AssignmentSetOverride) to the physical NIC registry path to isolate network hardware interrupts to non-gaming CPU cores, eliminating micro-stutters under heavy 2+ seat streaming loads.

By integrating these multi-session orchestration principles directly into Vibepollo's superior architecture, we can deliver a seamless, lightweight multi-seat gaming server out-of-the-box, saving budget and keeping old hardware out of landfills.
