We'll support most of ICE in Wildfire, Spark, and Smack -- at least
enough to get through firewalls whenever possible. We haven't researched
implementing the TURN proxy server stuff yet, so we're undecided on

However, a lot of clients probably won't implement even that amount of
ICE at first. I do agree that eventually we all need to get there.
However, the lack of good support even for STUN in a lot of SIP
environments shows how slowly this can go.

I think it's reasonable to assume that just about every server will have
a proxy service turned on for its own users. It will be the default
rather than the exception. I don't think many servers will act as open
proxies for anyone, but we shouldn't really need that anyway.
