For me aliases was just the tip of the iceberg. I know that there's
more than meets the eye in implementing cross-database support. At
the moment, I would prefer that the developement focus be on releasing
FB 2.0 and then merging of FB 2.0 and Vulcan to release FB 3.0. Then
maybe this feature could be tackled for FB 4.0. Unless someone
contributes the money to have it implemented in FB 3.0.
