The blocking efforts seem to be simple so far - don't resolve the
server address, block connections to the server, block connections to
the default port. The answer is to know of a friendly proxy, of

Not that that invalidates what you said - it's only a solution to
blocking at the client end, & making napster users find proxies (which
must be hard to detect by definition) should be enough of a win for
those who want to block it. When the above page led me to
