I was thinking recently. The new $30 AT&T iPad plan which gives you ‘unlimited’ internet usage could easily become a interesting way for people to torrent while on the move;).
However the main hurdle is that apple doesn’t allow Torrent applications into the app-store. I say, who cares!… Why doesn’t someone with bit of experience using c/objective c port the open-source torrent client Transmission to a publicly accessible repository where developers can compile it themselves and run on their own provisioned devices/their friends devices. Yea sure theres always the possibility of someone releasing a jailbroken application on cydia, but I am against the use of jailbroken devices due to some bad experiences I have had with the hardware playing up and the reliability of cydia in the past.
