Don't you think it a benefit that you are allocated a large block of
IPv4 address space if you support IPv6?
<draft-ohta-address-allocation-00.txt> says:
Usage Based Address Allocation Considered Harmful
The current usage based IPv4 address assignment policies might have
prolonged the useful lifetime of IPv4 address space but this has to
the detriment of the the end-to-end architecture of the Internet.
This memo proposes the adoption of an address assignment strategy
that releases large blocks of IPv4 address space into the Internet.
The objective of this policy is to encourage healthy Internet
deployment models with end-to-end transparency and association of
permanent connectivity with a stable IP address. This is intended to
encourage provider support for open transparent Internet service
environments that can be sustained with the adoption of IPv6.
and there will be some experimental assignment "soon".

That's why usage based address allocation is considered harmful.
However, deployment of the policy in the draft above makes it
real soon.
Of course, more serious problem is in multihoming but the solution,
as usual, is to rely on the end to end principle as described in:
