Here at Indra HQ we have been having some intensive discussions on architecture and the mechanisms of the cryptosystems and message construction and all of this sort of thing.
The end result is that there will be a substantial simplification of some parts of the design, that will also be more open ended, and that the names of things will more precisely convey the semantics.
And there will be many diagrams and tree structured outlines to explain things, and several helpful metaphors and analogies are starting to crystallise.
It is understandable to be skeptical when the documentation is sparse and poor and the main author is a bit of an oddball but I managed to construct the essential parts that make the rest possible.
Public demonstration of the basic relaying functionality will be our first goal. A web redirection to the official indra website will probably be the basis of the first demonstration. All relays will be set up to do this and the web page they land on will tell them which indra node they are emerging from.
