Maybe every space can at least have a geographic anchor for the enclosing building, then use a local grid reference system (x,y,z) to go from the building's anchor to the individual space.

Yes, I was thinking along the same lines but didn't want to introduce
more food for thought in my previous e-mail. A combined lat/lon/alt
starting point with an x/y/z offset seems a very useful anchor type.

I will, I just wanted to get some initial response from the mailing list
before tearing apart the wiki with my thought process. I'll probably get
around to updating it later today or else tomorrow.
