Can you give us a quick rundown of what the interoperable subset that you have is? Does it match your API? If so I'm in favour of drastically reducing the surface of our current draft (we were looking for reasons to do that at the f2f but alas lacked input).

For instance, if it's not possible to support searching on fields other than name in major deployed implementations, then I would be in favour of having v1 of our API just expose findByName("name") (do you at least have partial matches? Case-insensitivity?).

Are the fields that you expose the complete list of those that work everywhere? If so, we should trim. Otherwise, there's a call being set up with the Social Web people about what Portable Contacts Core could be (stuff based on vCard that works in a lot of places). I'll report as soon as I know more.

The thinking behind these questions is that we've discussed several times having v1 being the "quick wins, can be deployed quickly" version (for any API, not just this one) and have v2 be the "what we think should really be in this API" version (meaning that use cases would be satisfied by v2, fast deployability by v1). I'd like to call on your experience to provide feedback here, as being supported in PhoneGap and similar efforts is certainly a target.
