All of my games are available to everyone for free.
However, if you enjoyed any of my games, a couple of bucks to cover website hosting costs and support my ongoing efforts would be gratefully appreciated. I think $2 per game enjoyed is a fair price. Thanks.

I thought Google Docs did do general file uploads?
But anyway, I think Google should look very closely at DropBox, if not aquire them. It's a lot easier to use then Google Docs ever was, an allows me to write in whatever application (OO.O Writer, Q10 etc) that I feel like.
Heh, I think the difficulty in writing an App that works universally across the vast majority of Linux distros is far too hard =P perhaps that's why I'm sticking with Windows and Mac games at the mo ;)
