Really cool to see this! I'm sure the effort required to make it open source will pay off in fostering an active technical community. Given the target market I'm sure you have many highly skilled users who would love (at the very least) to fix their favorite bugs.
On a related note, recently at http://paperpile.com/ we've been thinking about ways to help our users connect their reference manager with web-based writing environments like ShareLaTeX. We've had some ideas about how to do this simply and cleanly, but I suppose now we could show you guys (via pull request) rather than tell now. :-)
We'd love to start pushing forward on some reference manager integrations, so a pull request would be amazing! It might be best to have a quick chat about how to implement this. My email should be in my profile.
