This BOF will discuss IMXP, an application-layer routing 
and how it may be used to support messaging and presence for 
applications requiring different levels of service.

A number of messaging systems operate over the Internet (and provide
useful service in doing so); however, each of these services relies on 
set of quality of service assumptions that limit its usefulness to 
applications. For example, the SMTP-based infrastructure provides 
extraordinary reach, but is inappropriate for either instant messaging 
(which requires very low latency between posting and delivery) and 
hardened messaging (which requires audit trails, reliability 
et&c). Similarly, although presence information was readily accessible
on Internet-connected systems years ago -- when a user had an open 
session to a well-known multi-user system, friends and colleagues could 
easily tell -- there is no standard way to make this information known 
to peers.
