If the same command(s) were to be used on every computer then you just
use ssh in a loop that iterates over the remote computers.  It's not in
parallel, however.  This is a sequential process that can be run from a
single computer.  

To do it in parallel you'd need a daemon that could respond to a
multicast packet with the name of the drive to mount/write.  Pretty easy
to do in C or Java (though I no longer have access to my examples). I
suppose there may already be a tool that does this but I don't know what
it is.
