How does the USRP2 get its IP address, how do you deal with multiple
USRP2 on the same
   host?  With IP routing, you'll generally need to have each USRP2/Host
combination have its
   own (probably very small) subnet, but you *do* have to get the routing
correct!

When you throw an IP packet "into the stack", the IP routing machinery
in the stack figures out
   which interface to send the packet on, based on the subnet mask
assigned to an interface.
   So you need to make sure that your USRP2 has a distinct subnet
assigned, so that it
   can be routed to appropriately.
