Sure! This is not my intention. I just want to make the local 
relationship so I can
reliably tell that the Peer I (with local device) connected to ended up 
in this
group and/or that one, no matter it is a client or GO.

Thus this Members property is not going to change, it will list peers if 
only the current
group is the GO.

Peer's Groups property will list the local relationship with groups, 
still in a local
scope. I am not interested to know any other distant relationships.
