Comment:

 http://dev.laptop.org/~gonzalo/activities/Write-87.1.xo have a improved
 version than show the activity is establishing the connection, and disable
 the abi widget until communication is established.

 This activity can't collaborate 100% times. I see many problems, but I
 don't know if is in the activity or in lower part of the stack.

 * At times, the collaboration is ok.

 * At times, both instances start but show different documents, and never
 sync.

 * At times, the changes in the joiner ar lost, but the changes in the
 offering xo are propagated.

 Other issue related with collaboration saw are:

 * On time, the activity was closed in both xos, but a Write icon continued
 in the neighborhood view until restarted the xo.

 * Another time, the python process didn't ended (see #4454). I needed kill
 the process before be able to establish another successful collaboration.

 I have tried with one xo-4 B1 and one xo-4 C1, first with os32 and later
 with os34. Also tried with "iw dev eth0 set power_save off" in the C1
 unit. I think is a little better but still there are a lot of fails.

 Then, while the _shared_activity issue is solved, there are something more
 not working.
