Hm,
If this was a forum I would suggest to move the discussion to a different thread :D
leo and
funzel are very right and as far as I followed the discussion here there is nothing wrong in "dual licensing".
The team only has to make sure, that the people contributing to the GPL version (I think there is only
one version anyway) assign copyright to the team (this is the
american term, in europe rights of use, modification, extension, adaption, distribution have to assigned
explicitely) otherwise the contributions fall under GPL alone and can not be redistributed under a different license.
E.g. see this company:
http://www.sleepycat.com/, thats a show case in the open source industry in
how to make business with the GPL.
There was a interview withthe CEO of sleep cat on /. some time ago … I'm sure you can
www.google.com for it.
