i doubt for porn but it would definetly work for cams
guys would buy at the bar the office etc $2 a min just like when they hang out looking at strippers, it's not too creepy, a guy whacking off to a cell fone or ipod is creepy lol..but a few guys choosing the hottest cam girl on a list and wanting to see her tits fully nude with an easy bill to fone option is gold
and screen size wont matter too much like with porn as long as its stable.
