I don't buy the "with no distinction" part, and if it is true, this setup
is braindead.

The flaw in PPPoE is the small MTU (but it's hard to avoid in the general
case, given what PPPoE tries to do).

I would very much prefer to have a PPPoA connection instead of PPPoE over 
an ATM tunnel - and it's clearly a lack of clue at ISP/telco that forces
me to use PPPoE at all - IMHO.
