Nick,

How about using ULAs as defined in RFC4193 ?

After all isn't local IPv6 FC00::/7 address block defined precisely for
such private use cases like the one which uSID requires?

Clearly RIRs will not allocate /22 blocks left and right and that v6 prefix
would be required if I have 1000 node network and my uSID is /32.

Thx,
R.
