[games sig] Downloader for shareware data files for gpl engines such as vavoom

[Hans de Goede]

Hi,

I had this idea last night, it would be nice to package doom (and other) 
gpl game engines, or improved spinoffs such as vavoom, but they are 
kinda useless without the shareware datafiles.

Now the shareware files are freely redistributed by a lot of sites, but 
nowhere there seems to be a clear license under which this is done, 
which makes things kinda dodgy.

Thus I had the following idea:
-write a program / script which gets started by the .desktop file
  instead of the game will do the following:
-check if any (registered, whatever) datafiles are present, if any
  found continue with running the game as usual/
-if not display a nice graphical dialog under X explaining that some
  data files are needed from say a CD and tell the user where to copy
  them and to press continue once the files are there, when continue
  is pressed, check again.
-Also offer the user the choice to download the shareware version for
  them as an alternative.
-if the user choices to download the shareware version verify the md5
  after download!
-after download completes ask the user to press continue.


So what do you think, I believe this is very user friendly, but is it 
legally ok?

Regards,

Hans
