Problem syncing Mobile account home folder

Question

I'm trying to get mobile accounts working correctly so that i can support users (including myself) having laptops and iMacs with files all in sync. My initial tests seem to go well, but when I started moving the first user account over (mine) I noticed a number of errors appear. Here is an example of what I'm currently working on (I've trimmed it down to just before the error message):

Now I've not done much with OS X programming, but I've done quite a bit of Unix systems work. The client appears to be getting an EAGAIN error (essentially that the syscall didn't complete, but not that it failed). Ideally, it should try again, and perhaps there is something I can set that will have it do a couple of retry attempts before giving up?
However, the error on the server side is the likely culprit. I don't know what the error message regarding com.apple.SystemConfiguration means, but my googling for hints implies that it is some sort of error connecting over the network. To try and debug that, I had both machines connected to the same switch with firewalls turned off and the error continues. The previous lines imply that it is trying to delete a file that it created from the local disk. What bothers me about that is that in the WGM I set the home directory to be "afp://servername/Users" and it shows that it should be either "afp://servername/Users/synctest" or "/Network/Servers/servername/Users/synctest" but the server is accessing the home folder directly, so why an issue with network reachability?
Can anyone offer any hints as to what I should be looking for? I had hoped that PHDs would solve the whole multiple computer issue, but they don't seem to be working reliably for me. Since I get this issue consistently I'm guessing that there is something misconfigured on my end.

Shawn,
I've done the deletion of those folders a number of times, with no luck.
The most recent attempt to get this to work was:
1. Delete ~/.FileSync and ~/Library/FileSync from the server machine.
2. With a brand-new install of OS X on a laptop, create a local administrator, join the server, then login as the user account that wants a mobile account
3. Look at logs
I still get an exception on the server

as well as the corresponding error on the client.
I'm quite frustrated with the whole situation at this point. I'm sure some folks have gotten it to work, but since it has exceptions like this silently, it slowly corrupts the data in an account. I still want to get it to work, but am skeptical that it will.
