It's not in the core. It would be great if it makes it there :-) It will 
be really easy to merge.
Since the architecture of OpenSim is so good (I've said this many times 
before!), the extension I made is really modular and simple. The only 
weirdness is having to subclass OpenSim.cs, so that I can instantiate 
the hypergrid comms instead of the default comms.

For this issue, I'm relying on probabilities & statistics! I hope the 
math delivers :-)
But I confess I feel a bit nervous about this too. I would feel a lot 
more comfortable if UUIDs would be suffixed with a domain name, or if 
they encoded domain names, so that ambiguity would be impossible, not 
just improbable.

 From what I hear, there is a distributed asset server in the making. 
We'll have to exchange some ideas.
It's too bad that the client is so attached to the one-mamma model. We 
need to constantly trick it on the server side.
