I agree, I wouldn't want to see a full complex beacons with meta data.
 Once bootstrapped any protocol (as you pointed out with JOIN) can exchange
whatever it wants.

Thanks for zbeacon Pieter, it largely addresses all my use cases, so it
seems like changing spec 20 now isn't needed.  ZRE can continue to be what
it is, I can easily listen for ZRE beacons and speak it's protocol when I
want to, and use zbeacon to accomplish my other goals.  I do still think a
little more service socket info in the beacon would be generally useful,
but it's not a blocker on me anymore now that I can use zbeacon.
