i'm just being nit-picky...i understand the design, and think it's pretty gosh darn cool, but they're definitely not going to work very well for a track set up...and one thing that i just now thought about: it would be a ***** to pull the rear wheel out of horizontal dropouts with a derailleur back there... eh...
as far as removing the wheel with a derailler, it's not that bad. klein uses rear-facing dropouts on their bikes, and once you figure it out ("wtf? why isnt't the wheel coming out? ooooooh. i see.") it's not so bad.
i've never seen cervelo advertise the possibility of using those two models as a track frame, but maybe i haven't looked well enough.
surly makes a 130mm fixed hub that'll work just fine. i raced on surly hubs last year, no complaints really. i dont understand why you'd have to have the wheel dished any different than normal. i'm also not sure i understand what you mean by offset stays. if the stays weren't aligned symmetrically the bike would handle like poo.
