It should - our intent is to support the Phi in both modes, so we would appreciate feedback. I'm going to post on the website FAQ some notes assembled by Tim Carlson and Michael Thomadakis about how to do it, and Nathan Hjelmn did the scif implementation, so hopefully others will chime in with suggestions as people explore this new capability.
