Hi Chang,

Thanks for the great summary!

Or a teleporter needs to know, if to use the warp pos hack. Totally 
unnecessary in OpenSim. Not sure, it even works!
A builder tool probably needs to know about max. size of prims.
And many many more...

You can improve your chances somewhat, by checking for 
".agni.lindenlab.com". But still heuristic and likely to break, I agree.

But a good one! ;-)
Love this idea!!
