The reason I started working on the JDBC driver was so that I could use
postgres for Spatial work with another project of mine. (I've been working
partly with GIS for the last four years).
Anyhow, on the java front, the other project is an astronomical toolkit
that uses postgres as a storage medium, and employs several GIS techniques
for chart generation.
Any how, I'm hoping to have the initial release of it to be out around the
same time as postgresql 6.4 is out.

I haven't got that far on the spatial queries yet (most of the work I've
done so far uses just points).
Also, the available functions are all two dimensional, and I will need
to handle spherical geometry in queries at some point.
