Jack:

        That's an interesting picture...

        If the LAN side interface on the right LRP box thought 
that its subnet was 0.0.0.0/0, then it would use ARP to find the 
MACID of anything that sent a packet from the wireless area. I 
could then setup proxy-ARP for the LAN side interface on the left 
LRP box to respond to anything that the right side ARP'd for...

        This will keep me up late. :) Thanks for the input. I
totally agree I'll be better-off simply using DHCP, sure. The
idea becomes more sellable (to the people I'm selling to) if I
could make this fly too. Thanks again.
