Fcp 0101 - update and clarifications based on feedback

[brooksdavis]

• Tidy the list of NICs to stay and add rl to it
• Extend the post-release feedback period (particularly since this is a .0 release)
• Assorted clarifications of intent

For the record, I believe this last commit captures the bulk of the discussion to date in arch@ and I anticipate there may be further revisions as new data comes in.
