Experience with Riverstone?  Yes, with a gun to my head.

My suggestion is counter to what you'd expect with Cisco or similar, but 
it works great for me.  Put a route map on the outbound side of the 
equation, and just permit whatever routes you want.  You can remove any 
"bgp advertise network XXX" statements, "ip-router policy redistribute" 
statements, all of that.
