You just have to make it appear to the NAS that you're doing EAP. You
don't actually have to *do* EAP.
There's no reason why you couldn't tunnel IPv4 so long as the packets
had a valid EAP header prepended to them. Send your EAP start, send the
identity response... then you can pretty much do whatever you like, so
long as it has a valid EAP header and the end server is in on the trick.
Had you got any special plans for this other than annoying
administrators by filling up their logs with very large EAP messages ?
