     Those methods are all very nice, but do not address the clients' security
problems.  Warm and fuzzy feelings that tor node operators, who often do *not*
put contact information into their torrc files, will oblige do nothing to
enable clients to avoid nodes running versions that are known to be unsafe.
     Either of the options that I proposed here *would* address this issue,
and the issue is one that calls for a solution.  The first of the two options
I suggested would also make it possible to distinguish between old relays that
have security vulnerabilities for exit service but not for use as entry or
middle nodes and old relays that are insecure for any use.
     If other options to deal with the problem are on people's minds, please
speak up!
