If you are interested, I am looking at dusting off GFC - unless anyone 
else can tell me where I can find a GPL'd C++ library for GIS 
objects..... I was planning on starting work in about a month - once I 
have figured out autoconf/automake and done a bit more reading. My aim 
is to start with a bit of recoding in the core mechanics using the STL - 
mainly so the code is a bit more intuitive for new developers, then work 
on making data types compatible with the GIS standards. However I don't 
know how compatible that development will be with the OGR code due to 
the different licences :-(

Know that feeling. I would go nuts if anyone permanently attached me to 
a digitizer or desk again ;-) I'll get back to you over the next couple 
of weeks about the indexing stuff - I need to revisit that anyway....
