Oh, that is a must watch for me, thanx. I remember Lunduke being vigilant because he was trying to sell his software on Linux without the risk of it immediately going into a repo for free (if I remember correctly). And why shouldn't he? I still think Linux would benefit from a strong offering of closed source software, as Lunduke did back in the day as well.
