Sendero experimented with an indoor GPS type system at the CSUN conference a few years ago. I do not understand the tech behind it, but it somehow involved flourescent lights.

There are to many flat plains and angles to cause multipath that will totally hose your signal. I'm guessing that tower triangulation would be a better method for building navigation althgouh that will experience many of the same issues. I've heard of in building navigation systems that use the lights as navigation elements but never used this. I would like to see better accuracy outdoors primarily. Places like San Francisco or other big cities can be pretty difficult.
