Question about replication options

I'm interested in having live replication from one server to another, and I've looked into many of the options out
therebut I'm unclear on one part of it.  The way our database works is that each individual user account has their own
schema. When a new user signs up, a new schema is created and populated with basic data. 

Slony-I seemed like a good option, but in the documentation it states that it "does not automatically propagate schema
changes." Our schemas don't change after creation, but I am guessing that adding a schema to the database falls under
thedefinition of "schema changes." 

Am I wrong about that limitation of Slony-I, and if not does anyone here have a recommendation for a replication
solutionthat would work for my situation? 

Thanks,
Adam
