Hmmm. First, you're forgetting that you need to read the data as 
well, ie make that 2/3.

I suppose you're talking about a software that makes up an image before
burning the data on CD.

Because RBSD is generally quite slow ATM (especially with SA), and 
there's also the task running taking time, background tasks etc.

Perhaps it's possible, but I don't think RBSD is the ideal platform 
for anything realtime at the current stage...

Kind regards,
