Speaking of source code, I've packaged up the Dot Comments code into a form that I'm comfortable releasing. I did a few stylistic changes as well as a bunch of commenting to make it clear what the code does. I also made it a little easier to use the code in a given application -- while the project creates the application Dot Comments, the EPCommentsManager class can easily be integrated into any app.

Clicky clicky for sourcey sourcey. Also released under the MIT license. If you do happen to use the code, though, it'd be nice (but not necessary) if you'd drop me a line. :)

FYI, icon not included, because it was not my creation.
