Re: winamp playlist question it wont display but plays.

Sometimes there is no logical possition in a stream. For instance, what 
if the stream is live from a DJ with turn tables, or whatever. Asking 
the server to maintain a buffer of the stream on the server side so the 
client can warp around, or press pause is asking a bit much. However, 
most streaming serverices do maintain dumps of their own streams but 
those are not always archived forever, and most certainly not to be 
relied upon since storage is expensive. Clearly there needs to be a 
distinction between live streaming, and streaming based on a collection 
of mp3 files. Mod_mp3 based on the notion of streaming based on a 
collection of mp3 files. On mod_mp3 it would in theory be possible to 
send the current file possition of the file when the stream starts, and 
possibly in a title stream. It would also, in theory, be possible to 
change mod_mp3 in such a way to tell it to start at XYZ possition in the 
stream. something like ?op=play&file=foobar&pos=4096. the pos= starting 
you to 4096 bytes from the logical begining (or ending) of the stream. 
Now if only that feature actually existed! Getting a player to 
understand how to send mod_mp3 these commands is another problem.  =)
