Good point. In general, it is probably best not to tie the Jingle 
session to presence so closely, so I may remove that note anyway. The 
only event that must be considered session-ending is receipt of a 
"session-terminate" message. If the other person goes offline by sending 
presence of type unavailable, you'll find out soon enough if the session 
is over (bounced packets etc.). You may consider the session ended at 
that point, but I think that's optional.
