[Sugar-devel] On Sugar 0.84 - status of the "Chat/collab leader" issue...

   So I was looking over the code with some of the #telepathy guys who are
also under the impression that sugar.presence code could be causing many of
the collab problems. Main issue is redundancy of code... a lot of what is
happening in sugar.presence already happens in telepathy (actually there are
even comments in sugar.presence code stating this) but until we know to what
level activities are using sugar.presence, we can't really do anything...
since activities would break, I guess we'd need to know what in the
sugar.presence modules is being really actively used to migrate to MC 5...
and give a warning or something, or keep some kind of sym links to the old
functions... I dunno, kinda above my level of expertise...
