As mobile does not support llDialog and HUD's, please create new, touchM, touch_endM and touch_startM, this would allow for scripters to cater for Mobile users to interact through chat with options selection, ex: touch hair, you get a msg, select 1 for blond, 2 for brown, etc and further on, user says 1, gets msg, for plain select A, for streaks select B, to end select 0 and so on. I don't know if touch on mobile differentiates between faces on touch, so as to make objects able to present faces with different options when a mobile touch is detected. probably a bad idea as mobile evolves, just my 2 cents.
