UIDocumentInteractionController support

It would be great if ShareKit could support UIDocumentInteractionController.

I believe for that the plug-in API needs to be enhanced to allow for plug-ins that share file URLs.

Can you provide some examples on how you'd use it?

My application handles PDF file. The user may either want to share / publish them or just push them to another application: Safari, iBooks, …

Currently my application has one "share" button. This opens a sheet with several options: Email, Open with…

I would love to replace that sheet with ShareKit to allow for more ways of sharing the PDF.

Currently this does not work because:

1. ShareKit does not allow for an "Open with…" option which triggers UIDocumentInteractionController
2. ShareKit does not distinguish between remote URLs and file URLs.
3. The UIDocumentInteractionController should only be invoked on file URLs
4. File URLs cannot be shared on Twitter, …

File URLs could however be resolved to NSData to be shared. I.e. ShareKit should enable all plug-ins accepting data rather than URLs.
