Regarding point 1, java.jdbc can accept a variety of types of connection maps. The simplest scenario is you pass in a map that contains the connection information, and you get a new connection and transaction for each call. However, you can also pass in live connections/transactions that can be reused. The with-db-transaction form is one way to accomplish this. It's really pretty flexible. (And btw, your library looks really quite good! I'm glad people are trying to address the issue of generating SQL within Clojure.)
