If someone can throw a demo package together, preferably under 1GB, and distribute it in common formats (Windows installer) that would rock. It should be pretty easy to, if time consuming. I'd do it, but my 80GB hard drive is currently at 79, and Freespace is not installed. Goober did a FSdemo for SCP a while back, throw in the necessary models (I think all the models but the Hatshepsut are now hi-polied), the textures (normal maps, glow maps, and all), tables and table mods (they'd need to be modified a bit), shaders, redone music, ect...
Then we can take the retail data off of the installer, maybe include a "where can I get FS2" link in it, we can become (finally) fully legit AND advertise ourselves more than ever before (with no fear of repercussions)
I think one thing that's always held our population in check is that we don't really want to advertise ourselves because distributing the retail data is of questionable legality.
