I’m still waiting for the missing “free” diagram editor for Mac. Or, even better: “Open source”.

Because most decent Mac apps become shareware once they hit version 1.0.

Also, there’s no doubt in my mind that all these utility apps will be web-based in the future. Google Docs and Google Drawings are great examples of this.

Having said that, I wish you the best of luck with your project.
