Spike: SignalR transport service

[sweetlandj]

Determine whether it is possible to create an ITransportService based on SignalR. The goal would be to see whether we could support async messaging from a Javascript client (i.e. browser) and a Pluribus server. It would also be interesting to see if SignalR could be used for server-to-server communications as well.

I like the idea of server-to-server communication over SignalR full duplex TCP instead of just HTTP. Is that still an option? Looks like it's doable: http://stackoverflow.com/a/21707322
