The reason why I brought this thread up is that I have read the current discussion in the Yahoo group, and remembered Bryan's earlier efforts. It seems that progress is a snail (pun inevitable), and the arguments have not changed much since 2009, but from time to time new tools are being published. Thanks to all the programmers and organizers, including Jon.

Jon, as for "w:", it is not really a stroke of genius; I would have preferred a syntax putting the syllable right in front of the note (like "=Should"C). But if programmers have only waited for some standard to become official, voilà.
