OK, so swapping out the URL's, and changing the broadcast method to "unicast", I'm able to get it to work - YEAH!

Only problem is that I can't get syncing to work, since it's just unicast at the moment. If I switch to "broadcast" or "multicast", it stops working. AARGH!

So, I'm wondering - could it be my router? I'm using a Siemens 4-port router, which explicitly allows for multicast packets. I shut down the DHCP server on my Linux box, thinking there was a problem there, and turned ON the DHCP server on the router, and no luck there, either.

Any other suggestions? I feel that I'm >< this close!
