Slony doesn't use much ram. The mysql clustering product, ndb I believe
it is called, requires all data fit in RAM. (At least, it used to).
What you'll need is disk space.

As for a cluster I think you are thinking of multi-master replication.

You should look into what others have said about trying to partiition
data among several boxes and then join the results together.

Or you could fork over  hundreds of thousands of dollars for Oracle's
RAC.
