Hi,
i sometimes real-time-encode long radio streams by piping the wav-stream to 
oggenc's standard input.
but for very long sessions this does not work, because the encoded file cannot 
get larger than my physical RAM memory (in my case 192MB ram, whitch is about 
220 minutes of music).
it would be nice, if one could encode music of about 24 hours without 
having 1,4 Gig of memory available.
