Hi Laurent,

I noticed you've been working on a moving the working bits of nbd to a
library. As you may have noticed, I've also been working on a dlopen()
plugin interface for nbd-server.

Since both your and my work seem to have the same end goal (of allowing
nbd to be embedded/used by external projects), I'd think it would make
sense to coordinate here. Right?

The goal of my plugin system is to write something where one could
write a module that would implement just the things needed that differ
from the regular nbd-server -- say, you'd implement an "open", "close",
"read", and "write" function -- and have the server handle everything
else -- multiple file support, copy-on-write, negotiating, etc. Or you
could just implement an extra virtualization option, so that a client
could get a different filename based on, say the phase of the moon. I
dunno.

I would think that such things could be useful for what you're trying to
do, as well; but since I don't know what your plans are, that requires
me to guess. Can you comment on what your goals are?

Thanks,
