Can't you just run a if statement? If it is a iphone/ipod touch (should be able to detect kinds of devices) if so show normal mud, otherwise, show mobile mud.
Also, I think mobile mud should just be its own subdomain, could make it easier. Man, I haven't toyed with vB in a while, or PHP for that matter, but I couldn't see it being that hard to separate. But no rush really, I know how it is being a forum/site admin.
