Hi Tim WHile I agree that DS does not have proxying capability (and should not have such a biest), I would expect that code making explicit use of OSGi JTA functionality (even implemented by the Aries JTA bundles) is very well usable with DS.
In fact, IIRC we once used Aries JTA in our commercial product without using Blueprint.
