I had a quick IM conversation with the developer of
Mover (which is out on the
App Store, but is also open source - check Cydia for the compiled most recent version). He said that it would be possible to implement the iPod library access API from 3.0 and then send music between phones.
I asked about himself coding this into the next version, however he said no as he wanted to keep the open source + App Store code the same, and as you can probably imagine, Apple won't want apps that share music with other devices.
I suppose where we are now is that somebody could pull down the Mover
source code, implement the iPod library access, and then at least we'd be able to send music and such between other Mover users.
Whaddaya reckon guise?
