Sounds good but there are a few reasons that make this hard to be done.
1.- FH require a powerfull CPU and GPU, a iPad is like an old computer.
2.- It still pending to make FH without bug for normal computers, both windows and mac.
3.- To do the game compatible to iPad, iPhone and similar, is not easy, even if Ogre gives support. It requires a lot of source code modification and a lot of effort.
Lets FH to be without fatal bugs for normal computers first.
