Wow this is great!
It's one of those things that I've been wanting to do from day 1, but 
given the existence of startup_commands.txt, it just got always low 
priority. But for events like this, this is really great!

For now, and given the 4096 problem, and the fact that there is a split 
distribution of OpenSim grids around 1000,1000 and 10000, 10000, we may 
need to channel this information through the regions that I am setting 
up in the UCI Grid. I mean, everyone can dowanload the link set from 
your web site, but if the regions are not in range, they need to go 
through the UCI bridge. So maybe we need to somehow expose the grid 
position, for the time being :-/

What a pain, this bug.
