If you ask me, you time would be better spent getting the
current code into "shape" so that it can be dropped into
aolserver as is.
The code on the branch is not really set in stone, so if
you can provide a reasonable way to add your stuff with
only a minimal change (like #ifdef AOLSERVER perhaps),
then we could add it in without lots of duplicated
functionality. Of course, it is up to you, but in the
long run 1 codebase is far far better.
One thing that we really should do is document the
init cases, we currently have three of four ways
a thread can go through the init code. It would
be nice to write each one down.
