good point...
I was projecting a mostly uninformed opinion that freq-hopping is
supposed to allow devices to avoid congested channels (along with
improving security and other cool stuff). So I agree that the phone
in question is probably not hopping, but rather, stomping.
Given that the requirements have been clarified to be "work anywhere",
then some kind of channel use detection on the motes' part seems to
be called for. I had a brief offlist discussion in re this and believe
that the TOS radio layers are not really designed to allow hooks to
do it at the app level. So a lot of low-code hacking is indicated.
Also the problem is similar to general ad-hoc net config dynamics,
exacerbated by the fact that you need some kind of comm to instantiate
the net and to gain time sync between nodes so channel detection can be
done to get hopping cranked up and working.
It involves a lot more game-theory than my poor brain-case can contain...

Why would a cheap cordless phone be smart enough to avoid the mote

The cordless phone doesn't "avoid" the mote at all, it stomps all over
it in a fight akin to Bigfoot stomping on an ant hill.
