In general, these options seem a fine way to partition the tor

during which clients and relays upgrade. Tor clients already don't
trust the relays. The risk is possibly more to the relay operator than
the tor clients using their relay.  It's their OS in most cases that's
at risk, not so much the Tor network.

An option to allow your client to only select from a list of relays
running a version as agreed by the DA's as recommended seems the better
of your a vs b.

We should stop talking about making the relay trust the client.  I
don't think implementing a DRM scheme serves Tor in any way.  If you
think of Tor like TCP, then the whole discussion gets silly.  Tor is an
anonymizing protocol on top of tcp/ip, for now.  Hidden services and
such are example applications that use Tor, the protocol.

Roger and I have had conversations about this thread in taxis, train
stations, and the like as we've been traveling.  I'm sure he'll comment
at some point.
