GRASS is the opposite of monolithic :-) It's absolutely
modular, you just need a few lines of shell script (or batch file)
to launch one of many commands:

http://grass.gdf-hannover.de/wiki/GRASS_and_PHP

Non-distributed GIS: You can run GRASS con clusters if you mean this
(I didn't read the entire thread, sorry).

mobile GRASS: In 2002, we developed "babyGRASS", a 2MB version
by just extracting the modules (commands) we needed for our
iPAQ devices:

(my hand in front of the scenic environment around Trento)

There was also a GRASS Server 2004
Radim Blazek, Luca Nardelli: The GRASS Server
http://gisws.media.osaka-cu.ac.jp/grass04/viewabstract.php?id=30
It came with voice interface - there should be a film somewhere
demonstrating how it worked.

A modern variant is PyWPS (Python Web Processing Service):
http://pywps.wald.intevation.org/
it has been written with native support for GRASS, using this
some client-server model could be invented.

Cheers,
Markus
