Erm, Jack...a Mavor doesn't ALWAYS pwn, as I've displayed to you on a couple of occasions. It has LOW HP for an experimental, and needs defending on every front since it's always going to be a target.
Since the bluetooth modem stuff is on most mobiles, I would assume you can. I'm not sure what the limit on data usage is though, I assume it's not too much at all.
It's a 3 Skypephone connected to my PC using bluetooth, on the £5 a month internet add-on. Works reasonable well, although I wouldn't want to game on it...
A recode for a new architecture minimal? PPC isn't the same as the PC architecture (remember the old Macs?), so the current code wouldn't stand a chance in hell of working. There's also the issue of the 360's processor being restricted to in-order execution only. I'm not sure whether that would affect LFS at all, but it certainly wouldn't help!
iframes...icky, and since you have no actual content there yet it's impossible to tell whether the code's working or not. I'd say clean up the layout (ie don't use iframes, they suck) and get some content in so you know that the pages load correctly
PS I'm not a web coder, so can't comment on the code you do have, but from a purely end-user perspective it needs visual work
