I don't know about inefficient. If you think it is than why don't you 
contact ZEro and Zha and Tess and so on to help them fix the design or 
at least have them explain to me why my analysis is off.

And as far as "never" allowing something goes, I never said that. 
However, an Agent Domain is in a unique position to do mischief and has 
to be at least as trusted as the most trusted external grid that the SL 
servers agree to deal with.
