I am very interested.  I have looked around for information on how to
do Joseki/Fuseki and I can find nothing that explains it in any
technical detail.  Either I'm not looking in the right place or it's
one of those little secrets the Go programmers don't share.

I will probably look at gnugo to see what they do about openings, but
I would be interested in what you (or anyone else) has tried.

I did look at some simple statistics for my program.  For my program
in self play I discovered that e5 is the most successful first move in
9x9 Go.  I considered doing an "opening book" by considering what the
most successful reply to e5 is, etc.  but this quickly leads to a huge
amount of computation to make a book just 3 or 4 ply deep.  A good
"book" would really not be very useful unless it also had responses to
all good moves (and even bad moves.)  Even with all kinds of board
transformations this gets out of hand real quick.  But even a 4 ply
"book" might help quite a bit I'm assuming.

I have no way to confirm that e5 is really that good except to ask a
good player.  e5 could be good only against itself, or maybe only
because the best answer to e5 isn't considered very often.  Since I am
pretty much a raw beginner myself, I am at a serious disadvantage
trying to make it play good openings.
