That does sound interesting. However, an iPhone app would only work on the iPhone OS. I think a better initial approach may be to get a mobile web version of the PerlMonks web site created, which would be more cross-platform compatible for more mobile devices. Of course, I admit that the mobile web version of the site is probably much easier to say than to implement.

If you're willing to shell out the money for the iPhone SDK stuff from Apple and to develop something, I'd definitely would be interested in checking it out while I still have an iPhone. (I'm planning to switch to an Android based phone next summer.)
