Announcing the Ink mobile framework

Android has been a discussion for us - it has Intents, so at least there is a baseline for doing inter-app communication, but it's still not as good as it could be.
In my case I had to build a system where it pulls from particular services (Dropbox, Box, Google Drive, Gallery, etc) or takes a picture from the camera. That is pretty straightforward with intents and you can either show every available app or specify exactly what other apps to allow. Also, we added an intent receiver so any app can share into ours. I have tested it across about 20 devices and have had 0 issues with the inter-app intents. The camera took more work but there are lots of libraries out there to solve the problems (mainly: where to store the file generated by the camera cleanly in all cases). Gallery also causes some issues because various vendors have re-implemented the gallery in non-standard ways, and remote URLs for Picassa or Google+ need to be dealt with, but it's not too bad.
If you are writing good quality code, fragmentation is completely overblown.
I played with an early prototype of this; it feels like it should have always been there very, very quickly. Worth trying the demos if you've not had a chance yet.
If Apple decides to levy a new API for doing interapp data sharing, doesn't this put Ink in a rough spot? Like, especially if it comes down from on-high that this is now the only way apps are allowed to talk to one another?
Second, people use products that are made by a variety of companies, not just apple. Being able to send content between apps and between devices requires an independent, multi-platform approach.
Yes, it's a concern, because Apple hasn't made your product core functionality yet, and no, it's not a big deal, because your larger product roadmap sounds like a platform for sharing content between apps on different ecosystems.
Looking for an acquisition by Dropbox?
EDIT: Don't get me wrong--sharp product, and good luck to you!
I'm quite excited to see this though - the end user experience looks great.
