about the tech part...i know that there are a lot of images...first time i gave a look at it i was frightened by the amount of stuff there:)
but i was thinking that with photoshop you can build a complete image for a screen and, if you have a precise reference (the m files) you can slice it and have the photoshop saving each slice individually (this is used obviously for web desing)
the different resolutions can be obtained just resizing the starting image (slices will be resized too...i think:p), we may also do a version higher than 1024x768 w/o loosing too much time
the probs would be the batch conversion of the images to pcx (i'm not sure i can save the slices directly as pcx), to have the precise slices, to convert to the right file format, the amount of screens, to substitute the vpfiles and so long...i never said it would be easy....but with a certain number of people working at it and sharing the wotrk it wouldn't probably and hopefully too pain in the ass...if done it must be a community project
obviously i'm thinking also about something very simple with the max amount possible of shared images, much much more simple than the original

interface, the main menu for example could probably be replaced by a simple console, most of the anis would be substitute with just one frame(static) anis, or at least with flashing buttons (example: to access at game options menu from the main menu there is an officer at the computers that rotate, this may be substitute with just a button that flash if you pass the mouse over it...) and so long
btw the demo would probably work better since there are all the artworks, not only the interface.....
just a little problem...if i remember well with demo you can't host dedicated servers (and - but not sure- you can't also host tcp/ip games too...and there weren't some little differences in the game engine?)
