Well thats obviously the logical choice. So far we force a device to
use an IP of our choice, however that breaks for at least the Moto Q.
This has an IP that seems to change randomly. Odccm has been modded to
let a user choose an IP, allowing the Moto Q to work.
Its also worth noting that if you want the PDA to get the internet
some apps will work with standard routing. Others need DTPT.py to
supply the Desktop Passthrough Proxy. Joy.

Are you absolutely certain?

eth3 is the WM6 device i just plugged in. It's the same with my WM5
device. What the hell is responding to the DHCP request???
Normally odccm forces the IP to the very ones that DHCP has offered.
Its always .2.1 and .2.2... But for the moto q it seems to reply with
general weirdness. If you do not comply with its wishes then you will
be beaten down... Or rather, odccm won't work.
One thought I have is that the phone has some kind of fake DHCP thing
going on so that windows can auto configure the device with an IP when
you plug it in - the values it returns might come from the registry,
rather than a traditional DHCP server. (This fits with some keys that
we have been able to change in the past I think).
