This issue alone means that shim6 isn't viable. Besides the already-
mentioned security and complexity issues, enterprise IT departments -
i.e., the customers who need multihoming and cannot live without it -
are not going to be amused when told that the tens and hundreds of
thousands of desktops, laptops, PDAs, and other IP-enabled devices on
their networks are now essentially routers, with multiple IP
addresses and complex middleware required to simply access 'the
Internet' . . . they're starved for resources and talent like
everyone else, and the network is -not- their business, simply a
means to an end. It's all overhead, to them.
Many customers have trouble simply supporting (and patching/
upgrading) basic OS and apps and IPv4. Expecting them to support
something like shim6 is as unrealistic as expecting them to re-
address at the drop of a hat due to changing business relationships
with their SPs (see RFC 4192 for an exposition on the effort required
to renumber, and discussion on the concept of network renumbering as
a frequent procedure).
