In Adium, so other protocols can benefit from it, too.

Theoretically, yes. Unfortunately, most ICE libraries just assume  
that you're implementing a phone client that happens to use XMPP,  
instead of an XMPP client, that happens to support VoIP. Because of  
this invalid assumption, all of them do the connection management  
themselves using the most minimalistic library possible (it's called  
iksemel, which is nothing more than a stream XML parser with some  
basic filtering support). The right way would be to use a callback- 
mechanism the application could plug in. This technique would allow  
using Smack for the non-jingle stuff.

No, jingle is a protocol that sets up the out-of-band stream (using  
ICE etc). Once this stream is up, RTP comes into play.
