Re : Deployment to Multiple Schemas

If you are just invoking sqlFile elements, the main thing you lose is the ability to have any hope of a changelog that works with different databases. That sounds like something that isn't a goal at all, so no big loss. If you were using something like Datical DB, you would also lose the ability to use our changeset wizard, the forecasting support, and the rules engine. 

Next question - the general way to make things like schemas vary in different environments is to use changelog paramaters. There is some documentation on this at http://www.liquibase.org/documentation/changelog_parameters.html
