Boot Camp Triple?

Ah, dear readers, it seems I'm guilty of a gaffe. No sooner than I made a post about Apple's Boot Camp being used to dual-boot a Mactel, it seems someone else has one-upped it. OnMac.net, the home of narf and blanka's infamous solution, has created a new hack that allows a triple boot.

Well, ok, it's only really a two-and-a-half boot. They hacked the Windows loader instead of fooling with Boot Camp, so you still get the OSX or XP choice at the beginning, but picking XP gets you to a second set of choices between XP and Linux (they used gentoo).

Still, it's pretty cool. I haven't figured out yet who would need to use all three on a regular enough basis to warrant having them all installed, even if said person was a software developer. Any suggestions?
