Are you referring to Sugar-compatible collaboration servers or generic
Jabber chat servers?  They are unfortunately far from the same thing.

Last year, OLPC provided a  hosted collaboration server for a time (IIRC)
at jabber.laptop.org.  Once there were more than about 50 active users
with B4 machines and emulators, the memory usage of the modified ejabberd
and general load on the server became so high that the system would crash
on a regular basis.  The task of solving that problem became Collabora's
current Gadget system, which is still in development.

Until Gadget is released, public collaboration servers are infeasible
because the server cannot handle the resulting load.  We could attempt to
create virtual private servers for various organizations to avoid the
scaling problems, but we have no access control mechanism, so we would
merely be hoping that not too many people joined any one server.  If they
did, that server would likely crash, and Sugar is not presently designed
to handle a server crash in an elegant fashion.
