Richard Morrell et al are contactable via the smoothwall.org website I believe.
It isn't feasible for me to browse a web site--could you tell me his email address, please?
The main "mover and shaker" appears to be Richard Morrell, who seems to count you as a personal friend. He did change the 0.9.9beta licence back to GPL, although I am not aware of anyone with the complete source.
Does this mean the problem has been solved (at least for now)? It could mean that, but I would like to be sure. Could you confirm?
Would someone please download all the available recent versions of SmoothWall and save them?
