I think you can exchange mozilla's (sunbird/lightning) calendar using MS 
exchange, zimbra and few other apps, but all that I found are not 
working under freebsd.
And this is what I'm looking for - server that support iCal and will 
allow mail clients (outlook, evolution & sunbird/lighnting) to exchange 
their calendars.
