        stuff that Emacs does magically find the SSH tunnel and work

+  Testing
+
+       noip provides a handy way for testing network servers and so on
+       safely.  For a start, you can run your test server apparently on
+       the same port as the real one.  Because noip consults the
+       environment variable NOIP_SOCKETDIR to find out where to put its
+       sockets, you can run two at a time and they don't interfere.
+       And noip doesn't care what port numbers your program tries to
+       bind, so you don't need to jump through stupid hoops in order to
+       test programs which use `privileged' ports.
+
+  Other applications
+
+       There are certainly loads of handy things you can do with noip.
+       If you think of one, let me know!
