To play devil's advocate...if you support GIF still, it should in theory be
possible to do something like extending the AIM transport to pull down AIM
buddy icons as Jabber avatars.  I realize the gateway transports are not a
high priority for design stuff, but there /is/ something to be said for it;
the more a transport supports of the legacy medium and translates into
Jabber, the easier it is to get general users onto Jabber without them
complaining about loss of functionality to legacy contacts.

Don't take this to be a strong argument in favor of keeping GIF, just a
sort of 'what if' circumstance being suggested. :)

I disagree.  I'm not sure it's necessary to limit to these functions, but I
think clients have to do image checking /anyway/ (or possibly reformatting)
because of the MUST qualifier on the image dimensions (between 32 and 64 in
each direction) and image size (8k).  Why not keep them to sane minimums
for the format as well, since you already have to be doing the checking?

This, I agree wholeheartedly on.  Plus, if 'animated' stuff including Flash
were allowed, you just KNOW someone would put together a Flash avatar with
irritating noises.  And then we'd have people seeing red and foaming at the
mouth over it, and there'd be a bloody rampage, and it'd be generally
unpleasant. ;)
