ah, I remember the slides from last battlemesh.

The "problems" in userspace are: we must maintain a global list
(so each node) which channel is the next best and we must time
the final channel switch. IMHO the specs are saying, that we must
switch within 30 secs after detecting the first radar-pattern.
Also we must mark/show the new channel somehow for new/crashed/upcoming nodes.
quite hard...
