+Summary: cache plugin
+
+A cache plugin is similar to a queue.  It reads data from its sink pad at
+whatever rate is possible, and keeps track of the buffers.  It pushes data
+to its src pad at the rate needed by downstream (if possible).  It keeps a
+copy of all buffers to make seeking possible.  Optionally, it stores data
+on disk.
+
+Uses:
+
+  fdsrc ! cache ! ... -- Mozilla pushes data to a plugin at whatever rate
+the data is received, and expects the plugin to take it.  This means that
+the cache is necessary to hold data before it is used by downstream.  It
+also allows downstread to seek, since fdsrc isn't seekable.
+
+  v4lsrc ! cache ! xvideosink -- implement simple seeking on v4lsrc.
+
+Options:
+
+  - parameters to show the min/max timestamps that are seekable in the data
+stream.  This could be used in a slider-bar widget that shows time elapsed
+in a player.
+
+  - parameter to cache data on disk
