well, the second nic would make your linux box a router, in the true 
sense.  think of a zone as a physical network.  you don't just 
separate macs into zones, like you would pc's into windows 
workgroups.  instead zones are a way to allow machines to talk to 
each other although they are physically separate (such as on another 
floor, or another building).  CAP may have a different way of 
seeding, the configs would probably tell you a lot.  you'll notice 
that the -seed option only works with multiple interfaces, in this 
case a nic card.
have you tried using both machines on the network @ the same time? 
i'd be interested in what happens.  my thinking is that the CAP 
machine would seed your zones, and netatalk might use them better. 
just another option.
