they are going to be something around 400Mb at the current encoding 
bitrate (164Kbps). A CD would be enough, but doing the math

  400Mb / 256Kbps = 3,5 hours

I doubt it that snail mail can be that fast ;-) [I thought it was much 
worse yesterday]

Actually, know what? the encoding is so slow that I could transfer 
while encoding .... hmmm, does anybody know how to do this? like a 
SSH-thru symlink?
