You could use our "EZ" interface to slice creation and maintenance,
which can just do this for you.  I just posted this to
planetlab-announce; not everyone gets that, despite its name:

    For resource management reasons in crunch time, dynamic slices are
    coming, whether you like them or not.  Here's a reason to like them:
    Rob has created a super-simple super-slick Web frontend to Emulab's
    interface to PlanetLab.  The frontend is not only EZ, it has a number
    of handy features.

    You can look at the two key Web pages to decide if it looks useful to you.

    This 2-line Web form lets you create a slice on N PlanetLab nodes,
    or on one node at each site, or on all of them:
       http://www.emulab.net/plab_interface_mockup/plab_ez.html

    The more advanced form is still "guaranteed EZ", but it lets you
    specify other stuff, like tarballs and RPMs to distribute to all nodes
    in your slice, a command to run on each node when it starts up, etc etc:
       http://www.emulab.net/plab_interface_mockup/plab_advanced.html

    Hopefully PlanetLab management will let us share their account database,
    and we're talking.  Meanwhile, if you want to use this, sign up
    for an account at http://www.emulab.net ; or if you already have one,
    ask us to set your "plab-ok" bit.

Also, if you update your RPMs or tarballs, you can push them out to
all your nodes with one click.  Earlier you asked about synchronized
command startup: that is coming soon, when we finish extending our
event system to the wide-area. What we have now runs when the vserver
boots.
