To pick just one example, here is what AS714 is sourcing:

    Network          Next Hop            Metric LocPrf Weight Path
* i17.0.0.0/9       8.21.82.85            80    110      0 65453 2914 
12182 714 i
* i17.0.0.0         8.21.82.85            80    110      0 65453 2914 
12182 714 i
...
If all active ASes did this we'd have a 400k routing table. So please 
no PI in IPv6, not even for large enterprises.

i don't think that's a realistic proposition unless you intend ford and
wal-mart and others with big enterprise-wide ip networks to use NAT when
connecting their desktops.  some of these people use direct peering in
addition to transit-provider-of-the-month, and that's a good model for
overall internet growth and robustness.
