There are always alternatives in the DB arena. Abstracting the DB interface
so that it does not strictly rely on Berkeley DB was all I meant. Attempting to
rewrite working code to make the DB layer more generic is about as much
fun as poking yourself in the eye (the SN code is guilty of this).

Sounds good, as long as #3 (or any other GUI front end) is left outside the scope
of the project. I think a key to success will be minimizing external dependencies
so that code can easily be incorporated into other projects. Then there is the
old C vs C++ debate and the discussion of which lame/broken compilers
should be supported.
I would be very interested in helping you get this project going. My initial focus
would be on a regression test suite and a Java parser. What comes next is
the age old question of labels and resources. This project will need a name and
a home. Sourceforge has some great features, but the mailing list archives
are really lame. I have always been impressed by the folks that run sourceware
(aka sources.redhat.com), but I don't know if it is the best place for such a
