Yes, I've read recently that they want to offer 1.5 via Steam, but that's not the point. I'm not against playing 1.6 at all, it's just that I have dumped Steam because it made my PC crash, so I won't be playing anything via Steam anytime soon, especially since I don't want to reinstall the entire OS just because of this piece of sh*t software. The only interesting possibility for me right now would be to be able to play traditional, non-Steam 1.5...
Thanks for your explanation concerning the IP addresses, I think I got your point.
Well, looks like I really have to dig a bit deeper into this matter...
