Another alternative is to use GridSQL. I haven't used it myself but seen it in action on a large install with 4 backend databases. Pretty slick.
We actually demoed this as a proof of concept a while back. Even just having two instances on the same machine resulted in linear improvements in execution speed thanks to parallel query execution.
Setting it up is something of a PITA, though, and the metadata database is completely arbitrary. You basically must use the GridSQL intermediate layer if you ever want to see your data again. I wouldn't use it for anything but a reporting database that can be reconstructed if necessary.
