Thanks! Tee is actually a pretty close approximation. For example, if 
you wanted to save to 2 files, you could do:

push!(p => p
    .encodeText
    .outputPipe(file1)
    .outputPipe(file2)
)

The whole advantage is that you don't need to use the output pipes as 
buffered output. For example, the convert function doesn't need them, it 
just pulls the whole thing (using the process function).

Everything is pulled with iopipe, even output, so it's just a matter of 
who is pulling and when. Pushing is a matter of telling the other end to 
pull.
