Correct, and this seems to be what the GFW is trying to do, just raise
the bar to make it difficult enough for the average user.  We've been
thinking about the arms race out to ten steps along it.  With China,
we're at step 2.  No other country, nor most American/European companies
that make censorship technologies are beyond step 1 (blocking the public
list of relays).

Trivial for a handful of connections and doing so at a countrywide scale
thankfully don't match these days.  Not to say a government can't tax
