  There has also been discussion at the Internet2 Multicast mailing list.


 And a couple of people have volunteered an alternative version 1.4 beacon and a dbeacon as at least interim beacons for the community to use.

But those are both down the road.  For the moment, anyone is welcome to use for a global dbeacon group.  Please limit yourself to 1 host per site, my end of this is a little, old, Mac mini, but you should be able to look here:
