The connection manager is interceptor based so it is pretty flexible.
At the moment you cannot plug in a custom connection manager, but this
capability could be added fairly easily.  I would need to know what the
alternate connection manager does before pursuing this.  I suspect you
are more likely to want to replace the entire jca subsystem or want to
improve the existing geronimo connection manager.

Tranql has generic wrappers for DataSource, ConnectionPoolDatasource,
and XADataSource.  For all of these you are going to want to write at
least a ManagedConnectionFactory implementation that exposes the actual
properties you can set on the datasource, a task that is apt to take
about 5 minutes.

Yes, using the tranql connector jca-jdbc wrappers.
