I believe you need to be an iCloud user running OS X 10.7.5 or higher in order to share a private calendar.

The calendar is on the iCloud server which i can share from logging in online. I want to know if a 10.6.8 iCal program can join it?

I believe you need OS X Lion (10.7.5) or higher, as stated here: http://help.apple.com/icloud/#mm6b1a8694.
