Tiger, Home Sync, and AD

Previously I posted a question about home syncing in OS X pre-Tiger release and wondering if it would be like AD roaming profiles. Well Apple introduces Home Syncing to the scene and it looked very promising, at first. This is what me and my counter part have found so far. 1.You have an user on the AD server. 2.You bind the Tiger client to AD and check the box for asking if you want to create a mobile account on log in. 3. On first log in you select to create a mobile account on the client. 4. Just for test purposes I create a folder on the desktop and set up syncing for Automatic. 5. I leave the machine for 15 minutes, check the server Home Directory and low and behold there is my test folder synced up all nice and perty. 6. Log in to a different machine with same AD configuration with same user. 7. Let the machine sit for a while because there is now syncing on log in. 8. Check server and all of a sudden the folder that I created on the other computer and was synced up is gone, poof. 9. My conclusion is that the Home Sync option only syncs up, does not sync down. Some one please give me some insight. My University will not get me Tiger server so I can't look in WGM to see if there is another piece to this puzzle that I am missing. Has anyone seen a way to customize this syncing for a log in log out hook? Thanks in advance.
