  PPPoE appeared with broadband Internet access services (Cable modem and
xDSL).  It is being 'forced' on the subscribers of some service providers.
I believe some of the short coming it is trying to solve is the lack of
authentication with DHCP.  DHCP was initially designed for a corporate
environment and not really a public network.  There is some work happening
to fill some of the gap.

  On of the concept behing PPPoE is that the end user and also the service
provider infracstructure is already establish to support PPP (because of
the existing dial up services)  They can reuse their RADIUS server and
probably all account management tools they have created around it.  Also,
in the case of DHCP you mainly have a 'pin down/static' connection.  One of
the pitch for PPPoE is that you can select different services by login as a
different user e.g. user@isp.com to go to my ISP or user@corp.com to access
my corporate LAN.

  So the FreeBSD folks were great enough to give us a PPPoE stack so we
could use our favorite OS to access the Internet via our PPPoE enabled
service provider (Thanks guys!).  So I believe the current implementation
is for the client side of PPPoE.  I don't think there is a PPPoE server
implementation and I don't think there is much use for it but if you want
to implement one...

p.s. I know a bit on PPPoE but I still consider myself a newbie on FreeBSD.
