GSoC Idea - XMPP

[Jan Kaluza]

Hi,
another interesting feature you could implement for Pidgin/libpurple
is Roster Item Exchange (RIE):
http://xmpp.org/extensions/xep-0144.html

It allows another user (but it's more important for gateways or
server-side services which want to modify your roster) to send you
batch of buddies. Then you can add them into your roster or just
ignore them. The main advantage is that with RIE there are also
nicknames and groups sent, so, for example, it allows RSS gateway to
send you all contacts in "RSS" group with proper names. It also allows
to update nickname or group or to remove it from roster.

I think this also can't be used as standalone GSoC project, but it's
just another idea :).
