in RFC 4408 I read

    The community is invited to observe the success or failure of the
    two approaches during the two years following publication, in order
    that a community consensus can be reached in the future.

Since the publication is apparently April 2006, the above implies there
is a deadline for April 2008. Is that correct? Should we provide a new
RFC by that date?

The most obvious amendment is, of course, that the protocol comes out
of its experimental status :-/

Yes, the IETF asked us to collect real-world experience after the 
publication of RFC 4408.  I think we should make another attempt at 
getting SPFv1 onto the standards track.

However, I don't quite see yet how the conflict with Sender ID's 
v=spf1/PRA abuse could be resolved.  We can claim that Sender ID and 
especially spf2.0 records haven't gained significant deployment in the 
past two years, but Microsoft could just claim the opposite and showcase 
a host of institutions that have allegedly implemented Sender ID (even if 
many of them probably have implemented just SPF and no PRA checking).

As for amendments to RFC 4408, I'm extremely sceptical of changing any 
semantics of the spec.  Maybe we can clean the document up and apply the 
handful of errata[1] that we have collected.  Adding receiver-side policy 
like you suggest in your other postings isn't something that I would do.
