Okay, I've come up with a proposed solution for the DHCP issue that I'm reasonably happy with. It consists of the following: 1) A udev rule which kicks off a script when a usbnet device is created. 2) A script (start_usbnet_wrapper.sh) that kicks off another script in the background (so that we don't tie up udev). 3) Another script (start_usbnet.sh) that: a) Stops NetworkManager from trying to configure the new interface. (Most distros use NetworkManager, right?) b) Configures the interface with an IP address. c) Kicks off a DHCP daemon to assign the remote an IP address. I ended up using dnsmasq (thanks Adam for the pointer) as it is a lot simpler to configure (actually, no config files needed) and I'm guessing it is more likely to be installed on people's distros because libvirt depends on it. But another option could be to use the simple DHCP server that I pulled together, if we didn't want to require a dependency on another package. Additionally, the script gets called when the usbnet device is removed and it kills off the DHCP daemon. I've tested this out and it seems to work pretty well for me.
