-DisOrder and Internet Streams
-=============================
+RTP Streaming
+=============
+
+DisOrder is now capable to transmitting RTP streams over a suitable network.
+To enable this make sure that allplayers use the speaker process, i.e. execraw
+rather than exec (or it won't work properly) and configure the network speaker
+backend:
+
+    speaker_backend network
+    broadcast 172.17.207.255 9003
+    broadcast_from 172.17.207.2 9002
+
+The destination address doesn't have to be a broadcast address.
+broadcast_from is optional but may be convenient for some cases.
+
+To play, use the disorder-playrtp client.
+
+   disorder-playrtp 0.0.0.0 9003
+
+Currently only 16-bit 44100Hz stereo is supported, which requires about
+1.4Mbit/s.  Possibly other lower-quality but lower-bandwidth encodings will be
+supported in future.
+
+If you have a too-recent version of sox you may need to set the sox_generation
+option.
+
+There is now (not well tested) multicast support.
+
+
+Icecast Streaming
+=================
+
+This can be achieved using the speaker_command option and Icecast (see
+http://www.icecast.org/).  It will only work if you use the speaker process,
+i.e. execraw for everything.
+
+I used:
+
+  speaker_command "ices2 /etc/disorder/ices.xml"
+
+where ices.xml is:
+
+  <?xml version="1.0"?>

+
+This doesn't seem to get on very well with pausing but you're unlikely to want
+to pause a stream in any case.  I used IceCast 2.3.1 and Ices 2.0.1.  You can
+play the stream with XMMS or whatever.  The total setup seems to play rather
+behind the 'current' time, watch this space for a fix (or contribute one!)
+
+If you have a too-recent version of sox you may need to set the sox_generation
+option.

+DisOrder and Republishing Internet Streams
+==========================================
 
 DisOrder doesn't have any built-in support for playing streams but you can make
 it do so.  I use the following in my configuration file:
