s/does/may ? ;)

Shim6 is work in progress and may be used as an argument to adjust 
adress-assignment policies sometime in the future. If we want ipv6
deployed today we have to provide a mechanism to support requirements
about redundancy and independence from individual providers.

I guess this relates to supporting infrastructure necessary for
shim6 to support or replace current ipv4 technology like 
load-balancing, filtering etc.  If standards are defined today
and everyone agree to implement them asap it will still take years
before such products are available and a commercially viable 
alternative. Shim6 has a potential to provide improved 
"granularity" in traffic management (individual path-selection
for each source-destination HBA-pair) but that is irrelevant until
the technology is actually there.

Bottom line: it's fine to develop technology for the future, but
operational procedures and policies must be supported by current
technology.
