"cpu" command, other related stuff

    Have a list of cpu servers stored in some variable (i.e. $cpus), and have
    the cpu command remotely check the load average of each cpu server in the
    list, and pick the one with the lowest load average.  This would allow for
    better balancing of jobs in a large multi-cpuserver, multi-user
    environment.

if you really wanted to do this, i wouldn't break cpu.  i'd write findcpu:

   cpu -h `{findcpu}

or you could use it to set $cpu at login.

i think cpu was intended to be used with a particular cpu server, not
just one with a low 'load average' [a totally foreign concept to plan
9].  the choice being based on a particular function that cpu fulfills.
