Sync Vista Home Premium with XP Home Edition

I would like to Sync files (over an Ethernet Crossover cable, or thru a wireless network) between a Vista Home Premium laptop and an XP Home Edition laptop. As I read the help file in Vista, the Home Premium version does support Sync over a network. I haven't been able to figure out whether XP Home Edition version supports Sync over a network.

1. Does anybody know if I can Sync between these two systems?
2. If it is not supported directly, does anybody know of a workaround?
3. If there is no workaround, can I find freeware that will do the job.
4. If no freeware, what can I (do I need to) purchase from Microsoft?

Thanks

I have seen a few inexpensive apps that file sync between computers. I would setup a shared hard drive on one computer and mapped the drive on the other computer to share files.
