Hmmm. Mabye we need new authors in fact I am working off line now to
find some authors. I was unaware anyone was actually working on IDRPv6?

Well we have a pretty good OSPFv6 spec out there now and I am hoping Rob
Coltun does an implementation. So I am not concerned if it later has to
be updated to v3.
As far as I-IS-IS that is a nice to have but IPv4 and IPv6 routing is a
bit different than tunneling IP in CLNP or the other way around.
Besides Dimitry's routing-aspects draft covers this anyway so my gut
feeling is I-IS-IS is not needed for IPv4/IPv6 and knowing it well I
would say this is just a matter of explaining this to customers as
education. As most likely the ones who want it are using I-IS-IS today
and thats not a lot of customers really. Bottom line is you get
integrated routing with IPv6 for IPv4 automatically by definition of how
the architecture was designed for IPv6 and the relative specs.
I am also hearing from Friends there is a draft on TAGS to use up part
of the flow-label in IPv6 and I innately have a real problem with that
and will be bringing that to the IPng WG list soon.

True... But IDRPv6 will provide a lot more to the telcos and ISPs.

I speak with a lot of customers and none have brought it up other than
in terms of DNS or LDAP to locate people not nodes on a network. In a
tutorial I do and have done for two customers I go over the history of
how all this came about. Both customers state what I just stated on
IPng and what Steve just responded, and that is but they cannot be
defined and I need more than one of them.
