As described in [//pipermail/tahoe-dev/2009-June/001995.html], the easiest kind of revocation to implement in a distributed, robust way is also the kind of revocation that I most urgently need: revoke the write-authority embodied in a specific cap.

The way to implement this is to define a special out-of-band symbol (i.e., something unambiguously distinct from file contents) which means "this file has been petrified". That would be a way to take a mutable file and turn it into a petrified file (formerly mutable but now immutable).

This is a requirement of #958 (LAFS 301 Moved Permanently).

Out of time to implement this for v1.7.0. I hope to add it to v1.8.0.

Out of time to implement this for v1.8.0. It is a forward-compatibility issue (at least I think so--I'm not sure Brian agrees) so I really do want to get it completed as soon as possible, but we already have a full load of other important issues for v1.8.
