Question: I've never fiddled with fifos before, so I'm just
wondering: as 'transfer' isn't explicitly created as a fifo, is it
considered a file, a link, or what?

So, this _should_ work if you're using extractstream/sendstream:

cd /var
mkfifo ty1

sendstream -s xxx xxx xxx xxx xxx | cat ty1

tivoftpd ## if it's not already running...

and go to another machine and ftp /var/ty1

If that wouldn't work, lemme know why not... I'd like to learn more
about these fifos...

Thanks,
