Given that we have an existing web based voting application that is
written in Python it would be preferable for any new vote counting
system to function within this framework. It's not clear to me that this
is the case with OpenSTV, nor that it's desirable to specify the
software means to achieve the desired goal as part of the board
resolution.

(I'm prepared to try and author a suitable ScottishSTV implementation
that fits in the current framework, but it will require either [or
ideally both] careful code review by someone else or a comprehensive set
of test vectors to provide confidence I have done so correctly.)
