Venue membership via soap?

[Thomas D. Uram]

Considering the difficulties we've had with the event service, and the 
concerns people have about losing their membership in a venue (and 
having their media tools shutdown), I was wondering if we should move 
membership management (i.e. heartbeats) over to the SOAP realm.  
Especially considering that the SOAP server is now multithreaded, this 
could be more reliable than the event channel, and would leave the event 
channel strictly to managing coherence.

This would simplify some services, too.  If they're not concerned with 
coherence, they don't need an event client.

Thoughts?
