Sync to separate idisk and calendar

[Ragnarog]

Hi,

On my iphone i'm synching to a "calendar and contacts" mobileme account (subaccount of my family pack). I'm sharing that account for contacts and the calendar with my wife and her iphone.

Now, on my iphone i can access "my" idisk which is on another account of the family pack.

Is there a way to sync my macbook to that idisk and still keep it synching with the calendar and contacts account ? (the idisk in question and the calendars+contacts are on 2 different accounts of the family pack)

Thanks,

Rag
