I have not heard of an open-source WFS as yet, but I will wait for
confirmation from Frank before assuming :)

Definately a complete abstraction is a nice end goal. Good modular
design will make all of this easier, of course. One thing I will be
looking at pretty early on (once you have built the framework :) is
putting OracleSpatial in there. Open interfaces to proprietary data
sources will help the general ecology of free software. I wonder if
there is a Java interface to SDE? If not a JNI connection could be used,
it would just be less pleasant. Doing the transactional stuff for
file-based data will be fairly tricky, I would guess, particularly in a
write-heavy environment.
