transfer IS a fifo, I forgot to put it in. : ) Think of it as I/O 
redirection, or a buffer, first in-first out. No bytes are lost if they 
can't be read fast enough, the kernel "blocks" I/O.

That would work fine. I use mfs_export because sendstream crashes too 
often. You -could- even use extract stream...twice. One time direct audio 
to /dev/null and video over ftp via fifo...and the next time audio over 
fifo and video to /dev/null.

If its possible to open two ftp sessions to tivoftpd, then you could do 
video and audio together. By nature of fifos and the video/audio 
relationship the transfers would stay synchronized. (extract stream isn't 
going to write more audio stream (in ratio) than video at a time, so one 
transfer will never "take" too much bandwidth, or one of the fifo's will 
start blocking I/O.
