I recall that the metaphor used to describe the Townsend Brown contribution to John's work was that in a different artistic medium. I did not and do not feel qualified to ask the questions which would allow me to interpret that in physical terms. And there has been a breakdown in communications with few people who might be qualified to know what questions to ask.
It seems to me that Nancy and John really should have a dedicated forum, so that they can have a central information release point and a historical discussion data base.
As long as that information exists somewhere else, it exists at someone else's pleasure. Forums get hacked, Admins get huffy. These things Happen.
