Is there a way to sync my ical with another person's ical?

Question

My husband and I both have icloud and we both have macs with ical on them.
Is there way to sync our calendars -- essentially to take all the info i have on mine and get it to his computer and phone, etc?

Answer 1

Correction to my previous note: [what i learned after trying it myself]
In order to save the Lion OS onto an additional computer in your home... you don't sign in to iTunes on their computer -- you sign into the App Store (under the apple in the upper left corner) on their computer.
Once you're in the App Store: Click on "Featured" on the top. Then, Click on "Account" (in the column to the right). Log in using the user id and password of the person/computer who purchased it.
(You can purchase one OS for the home and use it on multiple computers -- per the genius/tech guy at the apple store.)
Then, click on "Purchased" from the top row again (up there with "Featured") and you should see the Lion OS if you purchased it on your own computer. Click on "Install" and you're good to go!
Follow prompts to complete installation.
(Note: It may take a couple hrs -- and it makes a few things work and look differently, fyi.)
Once you've got both computers working in the Lion OS, you can complete your iCloud registration.
Now, after having install them, your computer should be syncing properly with your iPhone, etc.
To share your calendar, open iCal, Click on "Calendar" at the top and scroll down to "Share Calendar" -- You'll need to share each "Calendar" or 'category of calendar' individually with the person/people you want to share that particular heading/category of your calendar with... You do so by chosing who you want to share with and typing in their email. They'll get a notice on their iCal in a little box at the top (and a number in a red circle will show above the iCal icon as well). They'll also receive an email asking them if they want to accept or decline sharing a particular calendar with you (or 'so & so'.)
Either way -- once they accept it, all the stuff you've got saved in that particular category of your calendar will now show up on their calendar.
My husband and I are finally on the same page!! He can see all our plans on his calendar on his iPhone!! Also -- when sharing, you can select to have others be able to 'read only' what you're syncing -- OR -- you can allow them to "read and write." in other words, they will have access to the calendars you're sharing and they can make edits to them if you allow them to "read and write."
We are very pleased you can do this. I thought it was only possible to share calendars/have a mutual calendar with google calendar... Very happy you can share calendar info with others!! Woo hooo!!
