So how do you plan on doing that?

We know that IPv6 runs really well over regular ethernet or over  
tunnels. It doesn't work so well over the weird crap that broadband  
ISPs use which superficially looks like ethernet or PPP but isn't (and  
IPv6 over PPP is very problematic).

So basically your choices are giving them real ethernet, a tunnel,  
creating a world of hurt for yourself by pretending the broadband crap  
is real ethernet or getting a vendor to sell you CPEs that take care  
of the difference.
