Argh, they broke this too?
I used to use 127.0.1.0 as a virtual subnet via IP transparent proxy.
You would connect to 127.0.1.0 and your connection request would be
turned into a transparent proxy request in user space and forwarded
somewhere (in this case over an ssh port forwarding tunnel).
Linux 2.0 had some really cool features in its network stack. Almost all
of them are gone now. :-(
