You can jack your device to an lcd tv or use an ipad. I never tested it personally, but it should work.
Even without an Lcd screen, using those paper maps and miniatures is so uncomfortable that this is a good solution anyway. A map is just a reference, not the game itself.
we used corona sdk.
playing rpgs without having your friends physically there? eww....... that would like a mmorpg. and I hate mmorpgs.
Rpgs = Level up!
Mmorpgs = you become a zombie and loose all your Charisma points
