The reason I suggest looking specifically at the lp directory xmlrpc
queries, rather than ssh connections, is:

 * we do send the bzrlib version in the user-agent string and I think
always have since it was introduced
 * this query is sent on all connection attempts, including read-only
connections (but not by bzr ~>2.4, but that's irrelevant to this)
 * if it's not already logged by launchpad's http server it should be
trivial to do so
