&gt; Hi, I would like to know what data structures do you guys use in
&gt; your implementation of a nested coordinate system? 

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

&gt; Are you using R*Trees or a similar structure? 

Why, yes!

&gt; Has anyone played with R*Trees at all? R*Trees sound very
&gt; interesting but I don't want to spend time trying to code one to
&gt; then find out that they are really slow or completely inappropriate.
&gt; R*Trees are traditionally used to model spatial data for maps and
&gt; other such things. A mud does contain spatial data :).

If you look back in the archives there has bee some discussion of
R*-Trees and various other structural forms.  You may also like to
look for the neighborhood thread which proposed a significantly
different approach to pure geometry.

&gt; BTW: I am writing a text based mud but am planning to go with a
&gt; roomless approach. Building will be done in graphics (2D for
&gt; now). Anyone ever attempt this as well?

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