p2p. I think there are many projects that are working on just trying
to make more stable connections between two end points, independently
of whether they are participating in a p2p network.

difference between FASD and Plesh you are trying to highlight. I
mean both FASD and Plesh allow you to specify some meta-data, perform
a search and then retrieve a URI, that URI can then be used in
another network to retrieve a document. In my understanding of the
term "overlay network" it applies to both Plesh and FASD.
I'm not sure what you mean by "main linking structure". Sorry to be
a stickler on these terms, but I think that it is my understanding of
them that is at fault, and I am keen to clear up my own confusion.
To me the difference between FASD and Plesh is just the form of the
metadata. In Plesh I specify parts of an RDF statement. In FASD I
specify elements of a TFIDF Vector. In both systems I receive a set
of matches to the meta-data I have specified, both of which may
include URIs that I can then access from somewhere else ...
