There were a lot of questions, many of them from Alan, about reload's
previous architecture presentation.  The most recent revision to
reload introduced a new architecture model presented together with the
older model.

http://tools.ietf.org/html/draft-ietf-p2psip-base-00#section-1.2

The new model, referred to as the "overlay perspective" tries to more
clearly specify the roles of the various layer and establishes a very
clear parallel between the functionality of the overlay layers and the
general internet model.  In a lot of ways, this model is much clearer
than the old one.  It does have some drawbacks along the lines of
saying that TCP/TLS is an Overlay Link Protocol, which is a bit
counterintuitive to those of us used to thinking of TCP as a transport
protocol, but Overlay Link is more accurate for its purpose in reload.

We don't want to present two different architectures.  If we adopt the
new one, terminology in the remainder of the draft will be altered to
reflect the new model.  We would really appreciate comments on whether
the new model makes (or would make if the rest of the document is
updated to reflect it) the presentation clearer.

Henning has pointed out that "API" is probably wrong in the new figure
and those should simply be layered "Interface".
