I'm pretty sure we can sort this out without doing any of the above.
Resetting the network to a previous state will be much harder, and it
will involve reversing hard work that others have done, which is
something that you personally have said is not excellent, Jake. I also
think it's a leap to say the Vyatta is the gordian knot you want to
cut. While I understand your frustration, Ben has been working really
really hard on other Noisebridgian things -- setting up the lights
this weekend in Church for instance, for which he receives just as
little appreciation as your work on the MC Hawking. Believe me, that
whole thing is as frustrating as this is to you.

As a compromise, why don't we say that Jof does the low-level linuxy
things to get this temporarily set up, and then when Ben+Jof have time
together, they can work out why the magical configurator isn't working
and set something more coherent up? That means that Jof can do this
quite quickly, and Ben doesn't have to spend time on it, and can
continue working on stuff that he wants to, while you can too, Jake?
