It is going to be very difficult to offer a “full” peer through ‘just’ a browser. There are bascic cryptography issues that need to be addressed. Additionally, the offline storage capabilities are fine for actual offline experience, but conflict resolution requires a more advanced approach that is unlikely to be performant within javascript.

However, at long last, XulRunner is on the 3.x firefox codebase, so it seems like this would be a great target for the application. It can be built for some smartphones.

So that would suggest that either we could get XulRunner to compile on iPhone/Android, or we could get the extra components we need (likely git, CouchDb, GnuPG) running on those platforms separately.
