I've found that it runs well 98% (warning: very small sample size...) of the time in OS X -- every now and again it chokes for a second or two. Frustrating at game load when you're trying to get a good start going. No such hiccups in XP. That said, I have newfound respect for blizzard: I set up the 'grid' hotkey config, fully expecting to have to switch from Dvorak to QWERTY, but no! It autodetects the Dvorak layout and adjusts the grid hotkeys accordingly. Pretty badass.

I switched the January after my freshman year of college, for similar reasons, and followed a very similar approach. Just swapped the keyboard, and changed my desktop background to the keymap. Forcing myself to keep up old chatting habits ensured I had plenty of incentive to learn to type quickly again. I've just committed my passwords to muscle memory in both QWERTY & Dvorak, and somehow manage to be quite good at flipping between the two mentally. Probably has something to do with the fact the only Dvorak keyboards I use regularly are my MBP's and the external USB mac keyboard I have. Similar feel that is drastically different from other keyboards. For those considering switching, find a couple weeks when your work is in a lull, switch it, and just plow ahead. It'll suck for a bit, but (imo) is worthwhile in the end.

The first couple months after I swapped to Dvorak, QWERTY was a real pain. I'm now (3.5 years in) competent with QWERTY, though, obviously, not as competent as I am with Dvorak. QWERTY requires a little more looking at the keyboard. Long story short, continued practice does help -- having to log into public machines on campus has ensured my QWERTY skills are in decent shape.

FWIW, it works for everything...except fixing *heating* ducts. The dryness + the heat goes right through the glue, rendering the tape useless. Use as much of it as you want on AC ducts though.

Not to be too nit-picky, but recent (and ongoing) events have shown that the Iranians love/want freedom just as much (if not more; they're fighting for theirs) as we Americans do.
