I am quite new to Slony as well, but one of the first requirements the
docs state is:

  Thus, examples of cases where Slony-I probably won't work out well
would include:

     * Sites where connectivity is really "flakey"
     * Replication to nodes that are unpredictably connected.

So I suspect Slony is not a solution for your effort.  See:
