We need Jabber to be working too. For the infra scenario in the schools to work.
But if we consider Cerebro an important part of our future (at least I
do) we should dedicate more attention to it. I don't know about the
arrangements between OLPC and Collabora. It seems to be implied that
if Collabora works in the Jabber front it won't be able to work in
Cerebro. Is that the case? Really?
