Yeah, my understanding is that AtMail would need to own the copyright to
the product in order to have the commercial/closed-source version in
addition to the open-source "lite" version.  Either that or AtMail would
need to have the product re-licensed under an open-source license that
lets them take w/o giving back (e.g. a BSD license would work).

This does sound like something that all the current copyright holders
would have to agree to either way.  The only other concern would be
making sure that all dependent packages are licensed in a way that is
compatible with that dual-license scheme.

Just my .02 as a casual observer (and not [yet] a contributor).
