I just bought and am trying to download the D&D Rules Cyclopedia, and I find that even when I do so from a system directly connected to a university's trunk line, I'm only getting 1K per second download rates, or less. For an 80 megabyte file, that means it's going to take me more than a whole day to get it!
And to think I thought that buying it legitimately would be faster than getting a copy off of peer to peer... :(
