hi fustler-
the existing beta already does panoramic- just stretch the main output window until it's touching every screen you want it to take over, and hit the 'fullscreen' button. the aux. display plugin is intended to allow one layer (or group) per output- l1nk posted a screenshot in the 'other' section with something ridiculous like thirty plugins....
early reports indicate that both modes need heavy optimization, as performance drops when you start crossing graphics cards. we're working on it- keep in mind that these are just betas....
i totally jinxed it when i mentioned it ; )
