Yes, the summary is correct if you look at the effect.

Me too, that's what I meant with "what you are missing to your
luck..." above. We only differ on how we'd solve the problem.

Remember your original question was if it is possible. It is. And I
explained how. Yes, the solution is not perfect. But if you really
need this kind of locking, I cannot believe that a bit of developer
frustration is reason enough to not deploy Subversion (presumed
everything else meets your requirements).

I am not sure I agree on the method. Unfortunately I am not able to
give a technical reason, it's just a gut feeling. Maybe I can answer
that after some sleep. Regardless, I suggest you bring your proposal
to the attention of the dev list.
