we've covered hollows (tests are performed by the havok engine which
checks for collisions against the parcel wall) but alas, we DID forget  
about
llTargetOmega().  looks like work for rev2.

releasing this code is sort-of on hold, we've been hearing from the  
community
that sometimes estate owners do not want their estate content to be  
returned
when it overlaps a parcel  (think of Governor Linden's roads.)  so now  
we
need to find a solution here, and get everyone to agree on it, and...

but soon, yes, soon.
