The updated ULFM proposal has been attached to the wiki page:
The actual text on that page is out of date. I doubt that it will ever actually stay in sync with the PDF version unless someone generates a tool to make that happen automagically.
This version has updates based on the discussion with the RMA and I/O working groups at the current forum meeting. The remaining action items are to bring in some of the shared file pointer I/O people and get their input (Dries, Rob L.) on the most recent version. I'll send out a Doodle poll next week to schedule a time for that call.
The RMA sections is getting closer to finalized. The next action item on that front is to have a reference implementation.
Thanks,
Wesley
