I posted the following summary:
http://new.openspf.org/SPF_vs_Sender_ID
Executive summary
SPF and Sender ID are not the same. They differ in what they validate and
what "layer" of the e-mail system they are concerned with. Sender ID is
not the latest version of SPF -- it is a new and independent experiment.
The "spf2.0" tag name is a historical accident. Neither is better because
they address different problems. There is controversy because Sender ID is
gratuitously incompatible with existing specs. Microsoft is aware of the
problem and representatives of theirs have stated that they have no plans
to fix it. There are practical work-arounds for SPF users.
The remaining text supports the assertions in the summary.
