The problem with this is, there are some odd half-vac bans out there, some old false positives thanks to early versions of x-fire, and a number of other oddities. I have a friend who didn't hack, but he used x-fire, now he's vac banned on all non-source servers that are VAC enabled (IE HL1 based servers). But he can play on source. Ultimately though, it's a nice plugin.
