If you have broadband, search Torrentspy.com - you should be able to get it tonight.
If you want to own it, revok.com is selling copies, but they say they're closed for business while relocating and will re-open in early 2005.
Edit: Just checked Ebay -

It's a Buy it now, but I don't think you could possibly get it by tomorrow evening.
