[Simple] Draft on optimized presence federation

[Jonathan Rosenberg <jdrosen at cisco.com>]

I've just submitted an I-D that defines a SIP event framework extension 
called "view sharing". View sharing optimizes the performance of 
subscriptions inter-domain and is meant as an answer to the scaling 
analysis and requirements drafts we've been working on. The basic idea 
is, if there are ten watchers that are interested in the same presentity 
and will get the same presence document, have just one subscription 
rather than ten.

Here is a pointer to the draft:
