IETF MARID WG Sender-ID Judgment

The IETF MARID working group has come to a consensus about the issue I posted about here. They have decided that it is not wise to use a patent encumbered algorithm (in the case Microsoft's pra bit of Sender-ID). So what does this mean? Either MSFT will have to change the license on pfa or classic SPF will likely be what is adopted. Good to see that resistance isn't always futile.
