+Yes, it does. Any thoughts on this would be gratefully received. These

+It will automatically generate the .ASX or .RAM files that are often used
+in browsers. These files are actually redirections to the underlying .ASF

 stream should start 5 seconds in the past -- and so the first 5 seconds 
 of the stream is sent as fast as the network will allow. It will then
 slow down to real time. This noticeably improves the startup experience.

+You can also add a 'Preroll 15' statement into the ffserver.conf that will
+add the 15 second prebuffering on all requests that do not otherwise
+specify a time. In addition, ffserver will skip frames until a key_frame
+is found. This further reduces the startup delay by not transferring data
+that will be discarded.

+the amount of bandwidth consumed by live streams.
