Sure, though see #3 which can be stolen for lab usage as well.

For serious usage, I don't think the money involved is a major issues.

Already done, 2001:db8::/32 is set aside for documentation.

Setting up local v6 addressing for this reason seems like a bad idea
because there is no NAT and no global connectivity, so the box will
need some automated configuration protocol in any case.
