[bproc]bpsh and pipes

[Dan Smith]

I have two questions.  What does bpsh -n really do?  And how do you pipe
output from one program to another program while using bpsh? For instance,

bpsh 1 foo | bar

where "foo" is a program that produces large amounts of data and writes them
to stdout and "bar" is a program that processes that data and receives it
from stdin.  Using the above example as is seems to pump everything to the
master node and then back again creating lots of network traffic.  What is
the correct way to do this?  Thanks.
