Yeah. There actually already is some implementation of that in the code, since the GP2X devices don't have a keyboard. I didn't check that yet as its not important for N900. But if its ever to run on a keyboardless device, there would be problems because you simply need at least a few keys to play comfortably. But, at least on N900, where there is some free space on both sides of the screen, buttons could be displayed there that would emulate Esc, Tab (for map) etc. I'm kinda planning to implement this, but dunno if will get to it..so not promising anything.
