Why don't you use RegionHandleRequest? You can find esoteric stuff like 
this by searching through 
http://www.libsecondlife.org/template/release/1.18.2.0.txt, in this case 
I just searched for RegionID since it has been a while since I did what 
you are working on now.

Is this true? I wasn't sure if names were unique identifiers for regions

It does contain the global X/Y position on the map, look in Helpers.cs 
at LongToUInts() for an example of how to do the conversion. And if the 
sim moves, it is my understanding that the handle will change (and 
possibly the UUID as well, not sure).

I wouldn't make assumptions too quickly. A notecard gets a new UUID if 
it is modified, why wouldn't a simulator get a new one if it moved?

RegionHandleRequest. It is a lot easier than teleporting across the 
entire grid building a database! Believe me, been there done that ;-).
