It would be interesting to ipxe boot to RNDIS Android tethering nics... Combined with something like DroidDrive (to export an ISO as an emulated CDROM device to boot ipxe) you could some interesting things, possibly even emulating a keyboard to get the bios to boot to the usb/cdrom that contains pxe and using caching/squid to speed up network deploys.
