I think inside buildings is probably a lost cause for any device.  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.
