Is this what you are asking:
When you add an even in iCal, you can invite attendees of the event. Like, I have a phone conference with my kid's teacher Wed at 9:00. I can add my husband as as attendee of the event (as I am adding it to iCal on my Macbook) and then I can send him an invite. When I send the invite my Mac magically sends him an email notification since he is in my address book already. I tried this online on Mobile Me and it did not let me add an attendee or send an invite from there.
