<p class=MsoNormal>To be precise, the comparison is not really between the
hypergrid and Rex's avatar server; it's about comparing Rex's avatar server
with OpenSim's User+Asset+Inventory trio. <br>
The hypergrid is simply adding the capability of region servers interacting with
several of those trios instead of just one.<br>
<br>
So, the unclear spot, really, is why Rex felt the need to substitute UAI with
something else. <br>

This is an OpenSim discussion channel. So, we are interested in what OpenSim is
doing and where we are going.<br>
<br>
We have two different teleporting methods in OpenSim already. One is the
AWG/OGP which allows teleporting from the LL betagrid to an OpenSim region. The
other is the "HyperGrid", which allows teleporting between OpenSim grids
or regions.<br>
<br>
We certainly can consider a third, and that certainly could be Rex. Or, certain
Rex features may be added to the existing two interop technologies we already
support.<br>
<br>
So, with that in mind, lets move forward and discuss the technical details of
how the Rex technology works and how some or all of it is appropriate to add to
OpenSim.<br>

"Rex avatar server was out and TPing from SL to a Rex grid was done<br>
before LL made the gridnaughts. The Rex group is ahead of the curve.<br>
It probably will not hard for them to retool and go backwards to be<br>
compatible with others are doing. But you have to remember that Rex<br>
server is really the leader, the others are just following and not<br>
