It'd be pretty cool, but to be honest, you'd have to do a lot of HTML parsing and cookies and the whatnot to convert it to a mobile friendly site. And since you don't have access to the server side code, this might make it a bit more difficult. Doable, but difficult. If Blizzard allowed it, my plan of attack would be to have a PHP script or two to hook into the SMF settings/database so that we could grab the information rather than HTML parsing. Overall, the easiest thing would be to ask Blizzard to install Tapatalk but if I remember right he said something about it not working with the some of the personal mods he's applied to SMF.
