I would actually prefer not to hand the channel around. We have seen
devices where the channel changes every time they reboot and so it might
not be a good idea. I would prefer using a unique ID to identify the
service.

One of the bigger goals is a working SDP cache for these kind of task
and the knowledge when to refresh the SDP records for a specific
service. At the moment it is not fully clear how this can be achieved
and we might simply have to play with certain ways and see what works
best in the end.

Marcel
