I think you've misunderstood slightly here ... PAS was and is a Zope 2 
user folder implementation. It pre-dates Zope 3 (at least as we know it 
now).

PAU is a Zope 3 authentication infrastructure. I suspect it's inspired 
by PAS, but it isn't "PAS 2.0", or an "anointed successor" to PAS.

I find it interesting that Florian is planning to make it possible to 
use PAU utilities in PAS. I'm somewhat less convinced that it would be 
difficult to make membrane AT-independent. There isn't much AT specific 
stuff in membrane, as far as I can recall.

I can't make a judgement as to whether PAU could bring additional 
benefits, though.
