ok, so i'm planning on hosting a site purely for steam downloads and nothing else, not really a site - more picking your game to download and download it (Fast).
Im still not sure at the moment though, if anyone if willing to test download speeds post here and i'll get back to you with a download link for CSS (for testing download speeds).
PM me - I have lots more I'm able to share - i can password protect HD "SteamApps" and I could unlock HD with my Compressed files. All are Current (unless they are in Request thread on another STEAM share site)
it's pretty easy to set up. The server is actually your HD's and you unlock what you want. remember that when you announce that your server is up. If you shut your pc down - others might give you a hard time about it not being on (or up) much
the toughest part might be forward porting.I have a linksys router and give instructions for it. on that link.
