Have you checked out 30 Boxes yet?  Very cool application.  Looks like it could have some really good potential for a low budget solution to sharing calendars.  I heard about it on Scoble’s blog and actually watched a very interesting video podcast featuring an interview with Andy Barron, the founder of Rocketboom.

If you’re using a web-based solution for calendar, what are you using?
