[Vorbis] Random Writes

[Greycode]

Thanks for the reply,

Oh right, forgot about it being variable bitrate. Guess I could delay 
writing until I have an in-order sequence of blocks. I'm not really 
writing an application, just playing around with different things. So 
far I've just been using WAV, but as you've pointed out, CBR makes 
random writes easy. VBR does make this more interesting. Is there any 
dependencies on previous input?
