What I heard was that discussions broke down over Microsoft's patent licensing terms, which were incompatible with most open-source licenses. While their patent doesn't cover SPF itself, it covers some other related things they wanted included in the standard. Development seems to be continuing independently. If you want to follow along you may want to subscribe to the spf-discuss mailing list.
