User-space bandwidth shaping TCP proxy daemon
 iprelay can shape the TCP traffic forwarded through it to a specified
 bandwidth and allow this bandwidth to be changed on-the-fly. Multiple
 data streams to different sockets may be shaped to the same total
 bandwidth, much like a traffic shaping router would. However, this
 application runs in user space, and works by acting as a TCP proxy.
 .
 Here's what the author would like you to know: ip_relay sprang from
 the fact that I use a modem for home Internet connectivity, and once
 a large download has started, other Internet activities: telnet,
 surfing, VOIP, are largely useless. With ip_relay, you can suddenly
 decide to shape your downloads to 50% of your available bandwidth,
 and make use of the more interactive applications.
 .
 After using ip_relay for a while, it became obvious to me that it had
 another use: simulating bandwidth limits for other applications. Most
 notably was testing VNC over an ethernet connection, but at modem
 speeds.
 .
 The original software is called ip_relay
 (http://www.stewart.com.au/ip_relay/) but its name has been changed
 according to Debian policy.
