Yes, this is exactly what we were going to do with a product from
my previous employer. Unfortunately, there was downsizing, so the
product never saw the light of day. Nevertheless, I believe that we
would have been fully complying with the licensing requirements.

I can't say much more than the above -- just provide the required source
(i.e., Cygwin, PostgreSQL, etc.) which is *not* your application source
in this case.

Agreed!
