The Sequoia project is alive and well.  We have just completed (almost) 
version 2, in which GRASS utilities have been reimplemented as postgres 
functions operating directly on objects in the database.  (Version 1 
was the incorporation of GRASS data into postgres form.)  We currently
are working on some TCL/TK interface tools to access GRASS data and
functions.

Future work will be based on a new geodata model, instead of the GRASS 
raster/vector/site model.  This model is closely tied to the current OGIS
(Open Geodata Interoperability Specification) geodata model, as well as to
SAIF and SQL3/MM.  Geoprocessing functions will be rewritten to operate
on generic types of objects, which through encapsulation will provide the 
precise methods necessary to process the data correctly.

The geoprocessing activities in Sequoia, named Guernewood, are documented in
a series of reports which can be located at the anonymous ftp site
s2k-ftp.cs.berkeley.edu:/pub/sequoia/guernewood.  OGIS related materials
can be found at moon.cecer.army.mil:/ogis.  

Hope this whets your appetite!
