If you want to see what needs to be done to "integrate cerebro", then
please examine 

  http://dev.laptop.org/git?p=users/mstone/telepathy-cerebro;a=blob;f=tpc/service.py;hb=HEAD

When someone fills in those stubs correctly, we will have a Cerebro
connection manager. That ought to be enough to drive the mesh view. Then
someone will need to implement D-Bus and Stream tubes (not stubbed out
here). That will permit activity sharing.

The basic hang-up here is that our currently shareable activities are
built on Telepathy but there are few OLPC-related people who understand
and enjoy the Telepathy stack. Poly, according to his perogative, has
decided that building a Cerebro connection manager is not a good use of
his time. The Collabora staff most familiar with Telepathy are, at my
request, concentrating on Gadget for us for August. 

Questions?
