There *is* no problem with "IPv6 PI"...

My thoughts exactly.

The ASN's are the next problem that we'll hit. Lets hope that 32bit
ASN's will start working soon.

Yet again, my thoughts exactly.

I just tried to point out that the "IPv6 PI" is *not* a killer for any
solution like shim6. Some people then seem to think I have a problem
with the PI space..... oh well must be weekends ;)
