Connector and Slingshot Open-sourced and Free

Joyent's Connector web-based groupware has been open sourced. You now have a few options for open source, web-based calendar and email. I'm sure Chandler Server will be nice when it's finished, which should be any year now, and Novell has abandoned Hula so Connector is looking pretty good. Unfortunately, it doesn't have any keyboard shortcuts that I can find and I really need one-key archiving in order break my Gmail habit. [via Hack the Planet]
