To be honest my company has several apps up on the store and not sure this would ever be possible speaking to my techies for more reasons than I will list. To do with processor speeds, the way the ipad sections off memory, copyright infringement from microsoft etc. etc. I use iPad teamviewer so I can remote on to a pc in my house and can then use any game on my ipad although the screensize is a big issue.
Edit: looks like this is someone teamviewering on to me as I described - anybody wants I could replicate this on iPad 1 or 2 easily.
Well I would defo have it on my iPad 2
