[ppml] IPv6 flawed?

 How will you know their announcement is ULA-C to filter it?  Are you
saying that you will build a statement for every ULA-C for each ASN in
the world into your edge access-list?  Or is there some aggregatable
filter list I am unaware of?  Even if it were as few as 500 filter
statements, I would not be happy to have to extend an access list that
far, and I suspect the number of statements required would far outrun
that humble number.

Feel free to educate me, I want to learn.
