Using existing IM infrastructure has another serious advantage: most of the time
your communication is not solely by shared whiteboard/xournal. Virtually
everyone will also be on the phone or IM with each other while simultaneously
sharing a xournal page (assuming they're not in the same room).
It should be fairly straightforward to write e.g. a Pidgin plugin that launches
xournal and attaches it to the current IM conversation. See for instance:
http://xmpp.org/xmpp-protocols/xmpp-extensions/
specifically:
Jingle: http://xmpp.org/extensions/xep-0166.html
This specification defines an XMPP protocol extension for initiating and
managing peer-to-peer media sessions between two XMPP entities in a way that
is interoperable with existing Internet standards.

Feature Negotiation: http://xmpp.org/extensions/xep-0020.html
do you have collaborative xournal?
