[JDEV] more p2p & jabber File Sharing

[Kevin Smathers]

Hi Julian,

PASS is a streaming connection.  While streaming in and of itself
is fine, the proxy must be able to cache the transfer if it is 
going to act as I suggested.  In other words you would have to 
layer a file transfer protocol and caching protocol on top of 
PASS.

The other difference is that a second client must then be able to
request the same data from the proxy assuming it has obtained a
key that identifies the data that was cached.  In the second case
the proxy is now acting as the source; another proxy intermediates
and caches for the new recipient.

The poster was asking about downloading being the same as mirroring,
and I was trying to answer what would be needed to implement that.
PASS at present doesn't, although you probably could do an end-point
to end-point mirror through PASS (instead of end-point to proxy) if 
you didn't mind the wasted bandwidth.

Cheers,
-kls
