[MLB-WIRELESS] IP Addressing

[Tony Langdon]

I basically don't consider the wireless IPs a secure space - and yes,
encryption is going to have to take place before allowing any meaningful
communications.  Somewhere, some nodes are going to want to hand out
addresses to get the ball started (you want to reconfigure/reboot your
Windoze box everytime you get on a different part of the network?).

It might even be I use another address space altogether (10.11.x.x?) and
then have to tunnel into the network,,,  Haven't thought that far ahead...
