Has anyone attempted to make a Diigo App? What kind of interest would there be for an app for this?

I am thinking about taking a crack at it or co-creating it with an interested developer if you are out there somewhere.

If you have no idea what I'm talking about, check out diigo.com. Bookmark tool, Highlight tool, and Sticky Note tool for the web within a collaborative community. There is a FF and Chrome extension for it. Not sure about other browsers, but the desktop site works 'good enough' which is how i use it on the Pre. An App would be much more convenient and easier on the eyes! I personally use it for research and process documentation.
