Resources are not a problem (yet).
I want to avoid the extra connection (per activity), mostly because there
is no reason for it. The only thing that connection is for, is to
'register' a shared activity, by sending 4-5 of it's properties (activity
id, bundle, color, name). I find that this is a waste of resources.

For now, I think it would be best to make the protocol more complex on the
server side. This should eliminate the need for the extra connection. And
(thinking again for the future) it should work well with activities ran
from a normal browser (not inside sugar).
