there's already an android version of quake (which i believe is playable) so i think there may already be an iphone version.

inputs when all you have is a touch screen means that you'd die repeatedly if you ever did play a proper game against someone on a PC.

iphone apps supposedly need a mac for the various dev tools, which is a fairly major barrier for me. android looks easy enough if you can get over the required java stub code, set up the environment and then thunk through to native code (I started an fte android port, no sound and the menus might need resizing for touchscreens). For both systems you need gles capabilities first, as well as an engine that doesn't leak/need too much memory.

There's a Darkplaces iOS version on DP source, but I think it's in a VEEEEERY alpha stage.
