I gather there are lightweight jabber servers.

Thanks for the pointer, we'll have to investigate this carefully.
though Gaim as an upstream is disturbing given the feedback I've had
about their cooperation with individuals providing patches.  I also hope
their more recent code has a better UI; I always have found it
inscrutable.

I'll ask Khaled Hassounah to investigate; he just joined the OLPC staff,
and is expert at IM protocols (having helped found a company doing IM
protocols.

Thanks for the suggestion.
