Yeah, but think of the privacy and security that you lose.
If everyone has an OC-3, one can hack into one's computer and steal/delete/copy copyrighted legal documents with ease of use. As far as cheat-proof technology, you have to remember, it scans your computer for any malacious material that MAY be used as a cheat.
Take PB (PunkBuster) for example. It scans your whole Half-Life folder for any known cheats. From there I suspect it will only grow to be able to find something that even a default user will have on their computer. Then the computer-police come and arrest you for having malacious cheats on your computer. But I've looked too far into the future, I don't want to spoil it all for you.
No, this has nothing to do with Donnie Darko, case closed - he was a psycho that dreamt it all up, and so was that old hoot.
