There's now some more design strawman stuff for OGP IM in the Wiki; see 
the "simple design example" section on 
"https://wiki.secondlife.com/wiki/User:Dale_Innis/Group_IM_in_OGP".  And 
(although it's still just a strawman) it basically says pretty much what 
you're suggesting, for Vivox or IRC or GTalk or whatever: that OGP only 
needs to provide enough protocol for the viewer to correctly connect to 
the IM subsystem, and the chat itself doesn't need to flow over OGP. 

This seems rather sensible to me at first blush: there are enough chat 
protocols out there that it doesn't seem necessary to embed one into OGP; 
and on the other hand the intragrid does have some requirements that 
ordinary chat doesn't (like securely associating a chat username with a 
grid username), so OGP does have a non-trivial role in enabling it.  But 
this is all still very young thinking, and thoughts and contributions from 
all parties are eagerly sought.  (Don't let the fact that the Wiki page is 
in my userspace keep you from contributing; it's only there because I was 
foolish enough to volunteer to create the page.  I don't consider myself 
by any means the Sole Expert on the topic.  Dive right in!)
