I don't think it should be too bad. Justin started an H2 datastore,
see: http://svn.geotools.org/geotools/trunk/gt/modules/unsupported/h2/
I believe it's working, but not entirely done. He can go in to the
details of what's needed.
The only major thing lacking is a spatial index for H2. That's the only
unknown quantity. I wrote out what it may involve and links to relevant
resources at http://docs.codehaus.org/display/GEOS/H2+Spatial+Index The
most interesting is this thread in H2 awhile ago:
http://h2database.com/ipowerb/index.php?showtopic=212
I wouldn't think it would take more than three or four weeks, since most
all the pieces are there. But I could be wrong, as there are unknown
qualities, and a lot of pieces to fit together.
Just adding my 2 cents:
http://www.h2database.com/html/features.html#multi_dimensional
Those multi dim indexes could be used to index 4 columns with the
bbox, if indexing the geometry is not possible (I haven't investigated).
Cheers
Andrea
