there are a couple of other problems that I see with dt on the iPhone: - platform: google may be much more interested in seeing apps for the G-phone than they are for the rival (but then, a g-phone version may be much easier to do, and not worth a gsoc)
- barrier to entry: the student should have an iPhone (the simulator is only somewhat sufficient). - barrier to entry: the iPhone development kit costs $99 (that's not the SDK, which is free) and puts you through a few too many hoops just to order a development token for your phone, then much more stuff to put it into the AppStore. it's not pretty. i don't want to turn anyone off from the idea: if anyone thinks it's worth it go for it.
