Can I sync a single calendar to two separate mobile me accounts

Question

My wife and I have separate dot mac accounts and separate mobil me accounts. We each keep separate work and personal contacts and calendars on our computers and they sync to our separate I phones. We would like to have a single family calendar that will sync automatically through mobil me for entries made by either of us to the others phone, downlinking to our separate computers.
Is this possible?

Answer 1

Please read this entire post before doing anything, so that you can understand what you need to do.
My wife and I have the same scenario and I have a work around. Here is what we have:
She has an iPhone 3g and a Mac Book. I have an IPhone 3Gs and a Mac Book Pro. I have my Mobile Me account, and she has her own Mobile Me account.
Before you do anything, go to each of your computers and backup both your address books and calenders.
Here is how I have ours sync:
1) The 2 laptops are both setup under Mobile Me in the System Preferences under my Mobile Me account. In here, I have both laptops setup to sync the address book(s) and the calender(s) but nothing else.
2) On your computer, import your wifes backed up address book and calenders into your iCal and Address Book on your computer. Make sure that your wifes calender had a different name than yours in the iCal program. I mean make sure that your calender and hers was not both labeled something like "Home". My wifes is labeled "Her Personal" and my calender is labeled "His Personal". You can do the same thing for the Hers and your address books, by putting them in different categories before you back them up and import them.
3) After these are setup on your computer, then (a) go to System Preferences, and then (b) go to Mobile Me. In Mobile Me (c) click on the "Sync" tab. (d) Click on Advanced at the lower right hand corner of the window. Then (e) click on the Resync Data button. In the next window (f) click on the RIGHT arrow and the click replace. This will send all of the iCal calender(s) and the Address Book(s) to your Mobile Me cloud.
4) On your wifes computer repeat Step 3. Except, in step (f) click on the LEFT arrow. This will send all of the iCal calender(s) and the Address Book(s) from you Mobile Me cloud to your wifes computer. You are now half way done.
5) On your iPhone go to Settings. Then go to Mail, Contacts, Calenders and click on your Mobile Me account. Here you will need to turn on Mail Contacts and Calenders.
It will be setup a little different on your wifes iPhone however.
6) On your wifes iPhone go to Settings. Then go to Mail, Contacts, Calenders and click on her Mobile Me account. Here you need to make sure that only Mail is on. Make sure that Calenders and Contacts is turned off.
7) Go back to Mail, Contacts, Calenders on your wifes iPhone. Click on Add Account. Here you will need to add YOUR Mobile Me account information.
8) After you have entered you Mobile Me account information on her phone, go back into Settings and then to Mail, Contacts, Calenders and click on you Mobile Me account again. Under your account on her phone, turn off Mail, but turn on Contacts and Calenders.
9) Open both the Calenders apps on the 2 iPhones and allow them to update.
10) Open both the Contacts apps on the 2 iPhones and allow them to update.
You should now be able to keep your contacts and address books in sync on both computers and iPhones, but still be able to keep you individual e-mail accounts in sync on the seperate computers and iPhones. Please let me know if you have any questions.
