Hi all. I have a site that I put together for an attorney and he would like to be able to have a private calendar for each of his clients. Each client would be able to login and review his/her pertinent court dates etc. Can anyone offer any suggestions of where I could find an off the shelf option for this?

Thank you.

and the server side code and database server available is?

php & mysql

I've never used it, but it looks like VCalendar might be a good option. You'd have to modify the source to provide a different calendar instance for different clients, but that would be a lot less work then implementing this entire system from the ground up.

If you find any other solutions, please post them.

Why don't you use Basecamp and also include communications there as well? It's a great option for project collaboration if that's what he's looking for. Then again, it could be a little too complex.
