I wonder why epic won't do the following:

"We are now allowing the freeware download of our software Jazz Jackrabbit 2 and Jazz Jackrabbit 2: The Secret Files. We cannot suplly the game because we have lost it from our servers, and no technical support will be offered. All characters, music, and all portions of the game are still legally owned by us and we may withdraw the game from freeware status at any time."

I think I dreamed something about this... More legal garbage would be necessary but it would possibly work. I am quite sure a game can be freeware but you still retain all rights to it.
