Comment:

 I've created an OONI ticket #6804 for this, and it is being added to the
 bridge reachability test #6414.

 The way I have designed it thus far, it will work by doing:

 {{{
 $ ./ooniprobe.py bridget --bridges=bridge_ip_orport_list.txt \
        --transport='obfs2 exec /usr/local/bin/obfsproxy --managed'
 }}}

 exactly as one would set the ClientTransportPlugin string in a torrc.

 Will that work? Is there anything else which would be helpful, like any
 other torrc strings which should be set, or maybe parsing a file of extra
 torrc options?

 Also, because OONI and the bridge reachability tests are using txtorcon,
 and the spawned Tor calls exec, I am wondering what kinds of extra
 security checks I should use to make sure that exec doesn't get abused. If
 there isn't a way to make that safe, I will just include this option in
 the bridge reachability test in a separate repo, and not in the main OONI
 bridget test.
