Yes and that is an operational issue.

I'm supporting the position that the card is a device
eligible to be "addressed" in one way or another and that secondary uses
are not unauthorized by any policy. I would not support policies that
restrict uses of addresses for other purposes since it is technically 
only possible to use the addresses as designed, for network devices.

If others "key" off of an IPV6 address as an identifier, that's a
mistake on their part, but that shouldn't be a consideration in
allocating the space.

Again, I'll offer Cisco+VMPS as an example of this is not a unique
idea. I am hesitant to share my personal opinion of it though since
it is tough to see where the technical issue ends and the political
problem ensues.
