The hole discussion is about integration of Gluster in <some project>. I
would really appreciate to see the discussion in the public, on the
integration at gluster.org list. This is a low-traffic list, specially
dedicated to these kind of topics. Having the discussion in archives
will surely help to track the history of decisions that were taken. We
should try hard to prevent (removal of) integration surprises in the
future.

Let me know if you need any assistance with this, I offered to start the
discussion during last IRC meeting and am willing to follow through on
that if you don't have the time.

Thanks!
