I think there's some tipping point: you can comfortably do manual 
registration of some known public archive for scales of up to a couple 
of dozen people. At the scale of a major conference, however, that 
becomes problematic and DNS-SD/mDNS become very helpful. On the other 
hand, mDNS certainly doesn't scale beyond the local link. So we'd 
really need to see DNS-SD support in unicast DNS, which involves 
dynamic DNS updating, which introduces authentication issues... I agree 
that we should leave those aside for now, but that still leaves the 
entirety of the local link, and that still seems like it could be 
profitably pursued to me.

Yes, as long as people know about the NFS mount, make a new archive 
there, don't forget to branch before they leave, etc. All of these 
suggestions are the kinds of suggestions that make sense when you do 
NOT have a "global distributed namespace." They make a lot less sense 
when you do.
