We actually use a variant on this process here for v4 here. The registrar
sends them a PIN upon acceptance. Once they plug in and fire up the web
browser, the captive portal ACL pages allow them to use the PIN to create
their general purpose accounts, which they then in turn use to authenticate to
the machine registration system, which uses its local ARP tables (the system
happens to also be the router for the relevant subnets, but it could also
query the DHCP server lease database via OMAPI) to pre-fill the MAC address.
Quick, reliable, and requires zero administrator intervention.
