Don't know if it's best practice, but it works.  That's how I was 
running my cluster until this morning (just added two more servers, so I 
had to replace a crossover cable with a gigE hub).

Of course it wasn't really a crossover cable - just a piece of Ethernet 
cable - with autodetect, the DCE/DTE distinction no longer makes any 
difference.

Critical thing is to make sure you get all your networking set up 
correctly so that heartbeat goes over the new channel.
