SignalR on AppHarbor with multiple instances

Question

I'm evaluating using SignalR in an app hosted at AppHarbor running on 2+ instances (web workers) but reading around it looks like thsi won't work: SignalR wiki says that scaling in a web farm is still in development (and 2+ web workers sounds like web farm to me). Another question here on StackOverflow says it won't work on more than one iss server. On the other side, on AppHarbor support site they say it works great without giving much info thought (didn't answer to all questions like # of simultaneous connection, limits of load balancers etc).

Can someone confirm if SignalR is the right path to take on AppHarbor?

Thanks!

David Fowler is working on a Redis message store for SignalR. The code is on Github and I believe it is what will let SignalR apps scale to multiple AppHarbor instances.
