Rationale:

Bring flexible simulation of program execution to the browser.
Could be a useful tool for testing on injected account inputs alongside live data
Better debugging/integration testing

Features:

RPC calls made to fetch account data from on-chain.
Either port rbpf VM and build javascript scafolding to handle syscalls/account loading/CPI, or build entire message processor alongside VM in WASM and expose message processing entrypoints that replace account fetches to the account DB with RPC calls.

Challenges:

Perfect recreation of message processor could be difficult if done in JS.
Key is where to draw the line between recreation of accurate node functionality and ignoring in favour of simplicity.
