Scaling out SignalR

Support for scaling out SignalR to run in a web farm environment is still under development. The library has been designed with scale out in mind from day one however, and we expect to have solutions for scaling out via SQL Server and Service Bus in an upcoming release, as well as community contributed support for scaling out via other mechanisms (e.g. Redis).

Note: The previous scale out solutions provided in the source repo will not work with recent releases of SignalR.
