The last time that happened I was using different checkouts of wireless-testing
on both nodes and somebody had changed the code to match a new draft version
in between.

And the one time before that there was a bug in the ath5k code, effectively
preventing the device from beaconing.

If I'm not mistaken the draft standard says that every node has to actively or
passively scan for neighbors and automatically select candidate peers. A
candidate peer has to announce a profile (Mesh Information Element) in its
beacons that matches the local profile.

If manual addition of plinks is allowed you could theoretically force your
node to peer with a neighbor running a different profile, e.g. using a different
path selection or authentication algorithm, or an implementation based on a
different draft version.

I can't really think of an use for it.

Just my 0.01$.
