That's what I thought, but it's still tunnelling IPv6 > PPP > ethernet

ethernet.  From a functional view, there's no difference between 
encapsulating IPv6 in PPPoE vs IPv6 in IP protocol 41.  However, since 
they're modifying a router, which adds an additional step, they now have 
IPv6 > PPP, which is then carried by IPv4 PPPoE to Teksavyy.  This is 
necessary because they are not modifying the ADSL modem.  There is a 
similar router mod for the tunnel broker I use.
