This is essentially what we've done at my day job to provide a live demo.
We don't use user-mapping.xml, but we store a partially variable set of
connection parameters within a static JSON file and leverage custom
parameter tokens to define the variable portions, such as the IP address of
the machine chosen to fulfill the connection request and the username
assigned to the connection. The selection of machine is driven by sampling
system load, similar to what Vieri is describing.

It does require writing an extension but is definitely doable.
