I think I don't completely understand this statement.  It sounds like
you're saying MSN allows for custom emoticons, but that it just
displays a sequence of characters...?  Is that in Pidgin?  Or in
Microsoft's client?  Both?

Are you asking whether the underlying protocols support custom
emoticons?  Or whether Pidgin implements the functionality needed to
fetch and display custom emoticons for the protocols that allow it?  I
don't know the answer to either question, but if a protocol DOES
support custom emoticons but Pidgin DOESN'T, then perhaps it would be
reasonable for this scope of this project to include implementing
custom emoticons for a protocol or two?  You might need to install and
test the official Windows client for a protocol in order to determine
whether it supports custom emoticons.
