The contract between OLPC and Process One is in place to look at our
ejabberd issues. I've CC'd Jérôme at P1 so he might consider having
somebody look at this issue for us if there's time.

Jérôme, would you or one of your staff like access to either of our
servers on jabber.laptop.org (where most development laptop images
connect to by default, so 100s of users), and schoolserver.laptop.org (a
test school server at the OLPC office) for debugging?

Currently no, as Daf says we have a patch for it in #6295. Might it be
worth raising the priority of this patch for Update 1? dwmw2 said there
was also a concern in Mongolia with laptops (particularly teachers)
moving between identically-named but distinct servers (which is pretty
broken, because it means we can never connect those servers together,
but that's an issue for later I guess...).
