easiest route:
    for h in host1 host2 host3; do ssh $h 'hostname; date;'; done
...where the command to run is 'hostname; date;'

if you what it to happen simultaneously instead of sequentially, you can
do:
    screen
    for h in host1 host2 host3; do screen ssh $h 'top -b;' & done
...each ssh connection will happen is a different screen window. The
caveat is that when to process terminates, the ssh connection/process
stops. When the command screen evoked (ssh) terminates, the window
closes. I don't know how to overcome that off the top of my head. I
tried a few things. Will research more if you like the method.

Finally, there's an app called Cluster SSH, but it requires a GUI, and
I'm too hard to be GUI. Word!
