Technically, it is feasible. GRASS is GUI-independent and all modules
could be launched from within a Java-based GUI. GRASS is now also
cross-platform and if this would be based on version 6.4, then we could
have the same functionality on Linux/Windows and the Mac.

There is also a project that has come up with a JAVA API for GRASS:

http://jgrass.wiki.software.bz.it/jgrass/JGrass_Wiki

It does have, however, a very peculiar way of storing data in
"locations". All necessary data structures could, however, be created
on the fly in a temporary location as needed.

The final hurdle would be the GRASS topology model which is very strict
and refuses to accept messy data (such as overlapping polygons
in the same layer) that many other GIS tolerate (at least to a certain
point).

I agree that it would be brilliant to have the GRASS tools available
under gvSIG. There are now more than 400 geoprocessing modules in
GRASS and they are *very* powerful.
