Assuming I'm following what you're doing, the simplest thing to do would be 
to take one of your machines with 2 NICs, and then use virtual interfaces.  
You can have an arbitrary number of virtual interfaces associated with a 
single physical interface.

ifconfig eth0:0

can be used to configure them

I think you're using RH, right?  It supports /etc/sysconfig/ifcfg-$DEV:# and 
/etc/sysconfig/ifcfg-$DEV-range# files which can be used to configure lots 
of virtual interfaces.  Check out /etc/sysconfig/ifup-aliases for syntax.

Of course, it will also work to put 4 NICs into a box, assuming available 
expansion slots.

later,
chris
