Ok..TPC/IC im guessing is a sort of support for those who wish to run programs through the network (LAN: Local area network). If you load in the origional SC cd, you will be able to install starcraft, or a spawned version. The spawned version allows you to play it without the CD (this was made so people could play over the LAN without buying 2 copies). Then, using this comp (the one using the CD), I set up a Network game and then I looked for it to join it on the other comp..I couldnt find it. If you are really interested Just read my other posts (No-CD Advise). It says basically what I have just said..cept I didnt say it.
