I'm thinking of doing a Test Pilot study which probes various aspects of
users' Internet uplinks, particularly looking at "middlebox"
interference with DNS traffic (in aid of rolling out DNSSEC support in
Mozilla) -- it would be very similar to, or perhaps even replicate, the
Netalyzer experiment <http://netalyzr.icsi.berkeley.edu/> which uses a
high-privilege Java applet to talk directly to the network.
Is it possible, and practical, for chrome-privileged Javascript to
construct and transmit its own DNS queries? I get the impression, from
poking around the documentation for nsITransport and related, that at
the least chrome JS can acquire an arbitrarily-configured TCP socket,
but I can't figure out precisely _how_, and I would also need UDP.
thanks,
zw
