sharing data with iCal between more than 1 computer

[dtmdoc]

this may seem a silly question, but I would like to
be able to sync my calendar from iCal and address book too
between my iBook which comes with me to work and my
G4 867 at home. Both have 10.2.1, but is there a way
to be able do this? using rendezvous or isync?

thanks in advance.
