30 boxes debuted 4 days ago, and it rockz! Finally found my calendar service, thank you guys:

• Add new events through a command line (brilliant);
• Eficient Ajax powered interface, working in all browsers;
• Tag enabled events;
• Shared events, even with people outside 30boxes;
• Full integration with iCal and Outlook;
• Javascript/HTML badge to include a snippet of your calendar in other web sites;
• Will have an API soon.

Ahhhh, and it's free.
