this would be interesting. I might add that AGNPS has already 
been integrated in its native (FORTRAN) form by Srinivasan and
Engel. See

Sudhakar has already commented at SWRRB. I assume that you are familiar
with Chris Rewerts' ANSWERS integration in src.garden.

It should be of direct interest to quite a few. Others should be encouraged
simply because ("active model integration" == "viable GIS") is true.
However, I would be interested in putting together a WWW page summarizing
model integration into GRASS. Let's call it
  http://soils.ecn.purdue.edu/~aggrass/models/
It doesn't exist yet, but allow me a day or two and then give me your
feedback.
