Calendar server software suggestions

[AragonX]

Try Open Groupware:

http://www.opengroupware.org/

That is what I currently use.  It has built in support for Palm sync too.

Then there are:

http://www.egroupware.org/
http://www.phpgroupware.org/
http://www.math.utexas.edu/users/mzou/WebCalendar.html

Those are also good groupware products although I believe Open Groupware
to be the best of the bunch.
