:I'm currently using a variation on an R*-Tree.

I'm using localized containment and association models. No global knowledge
of locations, aside from propogation up and down the containment structure.
Which is good, because I also use lazy allocation.

:> Are you using R*Trees or a similar structure? 

:Why, yes!

No, but I've looked at them quite a bit, thanks to JCL...

:If you look back in the archives there has bee some discussion of

Thank you. *bow*

:Yup, except that I'm going 3D all the way.

Text, 3D all the way. (Well, I suppose a graphical client is possible, as
tokenized output does contain spacial data...) Building... well, yeah, I'm
planning to use a graphical building tool as well. No choice, there.
