There's nothing stopping Linux users from downloading it and repackaging it in a Linux friendly archive/format with different game and fred exes. I don't see the point of another 5 hour upload for what would be used by a small minority, when the bulk of the staff can't test it or work on it.
If someone wants to do that and can provide a download link, I'll even put it on our download page, but I can't officially support something the majority of the staff members don't have or use.
When we provide patches and additional content, such as about 20 or so ships I have ready for converting over to our textures we'll only be providing one version, as it makes things far easier for us to keep things up to date.
