Agreed on both counts: the presentation was great, and largely not
understood it seemed.

Notably, Alex and Tony both mentioned that the BGP tricks were not new
during the presentation, and commented that it would essentially not be
surprising to anyone that groks routing at the level that most of the
folks on this list does.

What was new though according to their presentation (and it was new to
me certainly, but I'm still fairly green) was the AS Path prepending to
complete the circuit, and as you mentioned, the TTL magicks to hide
the hops.

I was suitably impressed at that.
