RPXP web service

Rich Persaud has a web service that turns media clips into SMIL files [via Jon Udell].

Autometa RPXP/web is a web clipping service for RealPlayer, Windows Media and Quicktime audio/video streams.

If you know the URL of a stream (e.g. beginning with rtsp or mms), you can construct a human-readable URL that will clip that stream by start and stop times.
