The problem is that the mesh is entirely composed of people operating
the same way as you; if everyone only powers up the mesh for long enough
to scan temporarily for someone else's broadcast, then no-one ever finds
anyone else. You need to be sending out and listening for beacons in a
window that's going to overlap with someone else's in order to work out
whether you're in a mesh or not.
If we had a shared time source, you can imagine something along the
lines of "spend the first ten seconds of every minute sending/receiving
mesh beacons, and then stay powered off until the next minute if you
didn't hear anything".
