I would argue that when Steve, Matt and I invented it on the  
whiteboard at MCI, we were thinking about using INFO for out-of-dialog  
instant messages. We were also thinking of using it in-dialog for  
presence updates (using an INVITE-formed dialog).

But it mutated after it hit paper and the MMUSIC working group's  
review cycle.
