Re: [DNSOP] Updated NSEC5 protocol spec and paper

There are two reasons for splitting out the VRF

1) It is a useful building block

2) The intersection between the people who really understand the VRF math
and really understand DNS is very small

I think most DNSOps folk will want to treat VRF as a black box and let the
crypto folk put what they think is right in it and many of the people we
need to review the VRF are not going to want a lesson on DNS or NSEC5 use
of it.
