I'm not sure what the rpgmakerweb site has to say, but my two cents is as follows; if you have an android device, there's already an app that makes RMXP games run on the device. It's not perfect, and it has alot of work to be done to it, AND, the game author needs to keep in mind certain things when making the game if she/he wants to port it, but it's a start. The app name I believe is Neko Player, and I'm pretty sure it's free.. We've been talking about it a little over on Chaos Project too, and there's been a few problems reported and patches/workarounds discovered. I'm not encouraging you to go join over there just for that, but if you're curious, go take a look (If you really need it, I'm sure I could find the link somewhere =p ).... Now if you wanted to put it on iOS or WinPhone, well, I'm not sure... I know that there's some XDA tools that make it alot easier to port games for windows phones than it is to iOS devices, but I think it would be a matter of preference at that point.
