SIP in higher education

[Candace Holman <>]

The article that Bill Reid posted does indeed go on to compare SIMPLE 
and XMPP.  Peter St. Andre's main complaint about SIMPLE seems to be the 
IETF.  I heard it was true that SIP's main complaint against H.323 was 
the ITU.  My question is: is this a protocol war or standards body 
friendly fire?

St. Andre says that SIMPLE is the biggest misnomer there is, but he 
doesn't really give any examples.  I've read standards (ok, excerpts) 
from both SIMPLE and XMPP, and while the XMPP standard documents are 
simplistic, does that instantly make them simpler to implement?  Does 
simplistic mean that XMPP wins all the performance and interoperability 
races?  Is it easy to troubleshoot a problem, manage users and devices, 
patch with updates, add custom development tweaks, or integrate with 
campus databases?
