A chandler could receive more than one channel, so for Process method
and Dispatch signal we need an ID to tell which channel we wants to
process/dispatch. And we can't just use the TpChan+TpConn objects
because for Tubes one channel can contains many services handled
separately. So I think the easiest way to solve that is to generate an
unique ID for each channel dispatched like and once it's dispatched to a
chandler we use this ID for future communications between MC and

I agree we can rename "Process" to "Dispatched".

One thing I forgot in my proposal is a field in .chandler file to add
some capabilities. For example the voip-ui will install a .chandler
telling MC that we have a voip ui so MC should announce a VoIP
capability. NMC already does that IIRC.
