PPPoE usually implies crappy ADSL from the likes of Bell Atlantic and other 
unscrupulous monopoly-weilding companies.

It is usually so SLOW that doing NAT and Internet over the same interface, 
even on an LC III, will still be faster than the line itself.

It is with cable modems and other forms of real DSL that require two ethernet 
cards (my cable modem gives me up to 500k to 600k a second for things like 
downloading Netscape or other piered networks).
