Of course not.  But multi-homing customers are only one facet of the
picture - the other side is customers that just find it inconvenient to
renumber when changing providers, so they go for PI, if that is more
convenient (and we see this already happening in IPv4 in Europe - PI
assignment rates have been going way up in recent years).

Given current multi-homing technology (BGP), the number of participants
doing BGP-style multi-homing is "somewhat limited" (because not everybody
can run a BGP router yet, and ISPs do not usually offer BGP on DSL- or
cable-style products yet) - while the number of end-users that would 
prefer to have a sticky IPv6 address and never having to renumber is 
virtually unlimited.

And I direly want *those* to use PA space - and see that aggregated.

For the multihomers, it's very hard to make generic statements, as the
differences among these networks are huge.
