See my comment about direct hookups. My experience is that they are 
prone to playing up for no apparent reason (NICs simply aren't designed 
or tested well enough for this kind of connection mode)

Managed Gb Switches are pretty cheap compared to the hours you'll waste 
trying to make it go. Put a couple in between the servers.
