+<h3>Developing polypaudio Modules</h3>
+
+<p>There are several reasons for writing loadable modules for polypaudio:</p>
+
+<ul>
+ <li>Device driver support in addition to ALSA/OSS</li>
+ <li>Protocol support beyond ESOUND's protocol and the native protocol. (such as NAS or a subset of aRts)</li>
+ <li>New programming interfaces such as XMLRPC or DBUS for controlling the daemon.</li>
+ <li>Hooking audio event sources directly into polypaudio (similar to <tt>module-x11-bell</tt>)</li>
+ <li>For low latency applications such as VOIP: load the VOIP core directly into polypaudio and have a slim GUI frontend to control it.</li>
+</ul>
+
+<p>There is currently no documentation how to write loadable modules
+for polypaudio. <i>Read the source, Luke!</i> If you are interested in
+writing new modules feel free to contact the author in case you have any
+questions.</p>
