syncing iMac and macbook

Hi

I have had my intel iMac for about a year and a half now. I am looking at getting a new macbook too now. Is there a way to easily sync certain things on these devices?
Mainly iTunes and iPhoto libraries really - ideally items added on either would be propagated to the other device when on the same WLAN, but I could cope with only being able to add items to one device with that pushing content to the other). Email would be a bonus (no - I don't want to use imap accounts - just keep my pop3 ones). I'm also considering getting a timecapsule if that would help matters.

I have a mobileme subscription too.

Am I hoping for too much here?

thanks
Dave

yeah think the easiest way is to use time capsule or a standard ex harddrive!

sounds like effort tho - bit too manual. I've found this which might do it for iTunes:
