hub spoke model

I attended a presentation in April at the Seattle XML-SIG meeting by Christopher
Jones of Planet 7 Technologies that touched on that very subject.  They've been
working on an XML server product that gets away from the hub-spoke model.  It
does real-time XML interactions, without passing the entire XML document back
and forth through a central hub.  I checked their website, and evidently they're
preparing for their product release, and so no information is available.

If I'd known I was getting a pre-announcement preview, I'd have taken better
notes!  However, I remember at the time that what he was talking about struck me
as being very much like Domain Name Service, in that XML Server X doesn't know
anything about XML Server Z, but it does know XML Server Y, who happens to know
Z.  And so the data makes it around the circuit.  They have, as I recall, two
modes of propagation.  One is a "broadcast" mode, which does nothing to ensure
all parties get the XML, and another that certifies that the XML gets to the
intended recipients.  I wish I could go into more detail, but the architecture
was more like a tree than a hub-spoke model.  Trees could be joined together,
and they didn't necessarily have to be joined at one point.

Subject:  what Napster means for XML

Has anyone done XML-specific work toward these kinds of architectures?
