As one of the authors of this protocol, I'll also mention to be complete
that this is an informational RFC, which has a different standing than a
protocol that has gone through the entire IETF standardization process.
At the time, we had a problem that needed to be solved, but wanted to
esure that the solution was an open one.  Much of the work was happening
within the ADSL Forum (imagine the cantina scene from the original 
Star Wars movie, and you'll get a sense of what I thought of how well
that body works).  Since work done in the ADSL forum (e.g, documents) are
only available to ADSL Forum members at $6K a year, we (e.g., UUNET along
with Redback Networks) decided to publish it within the IETF, and then
reference it in the ADSL Forum contribution we made.  Essentially, it says
"See RFC-2516 for how it works."

The success of PPPOE in the marketplace doesn't seem to have been
hurt any by the status of the RFC (for example, RADIUS was also an
Informational RFC until very recently).  It's been widely adopted by
lots of folks.

I've got one of the Linksys boxes, and they work pretty hard to hide what
runs inside.  (If you're not familiar with the Linksys box, it's a 
box with an Ethernet "uplink" to the Cable Modem or DSL box, a small
router or NAT, and a 4 port ethernet switch on the "local network" side.)
If I had to guess, I'd say it ran Linux since some of their other small
boxes seem to run Linux.
