that is pretty funny. especially if you
imagine keanu reeves saying it… “whoa,
i *know* vi.”

For a good discussion of anonymity on
the internet, you may wish to read
about “the nymity slider” [this is
the horse's mouth version:
http://www.cypherpunks.ca/~iang/thesis.html
but there are no doubt shorter versions
around somewhere.]

In addition to Ian Goldberg’s work, you
can also look up “TOR router” or “onion
routing” for more discussion about
anonymity on the internet.

You know your derisive friend actually
works at the lab traceroute [and quite
a few other "internet tracing and
measurement tools"] came from.

You might also want to read about NAT. Especially before going wild with nmap.
And pointing nmap to random sites is
usually considered kind of obnoxious.
