As far as I understand the idea behind the Adobe Debut - application that is designed to present ideas and projects - it makes sense to add native DLNA streaming support. That way, one would be able to present wirelessly, walking free in front of audience with all the annotation and interactivity goodies of Adobe Debut, while being connected to DLNA supporting device (wall projector, huge TV setup, DLNA->HDMI media server, etc...). It would make it killer app not only for presenting ideas on meetings with client or manager where both people can sit in front of tablet, but also on big events - which for now requires us to connect trough hdmi or other wired setup.
While as far as I know on Android platform there is no way to stream whole desktop without rooting the device (and sometimes loosing warranty) or being connected using USB cable, it should be doable to stream single application window. Simple solution would be to capture the view every 1/nth second and feeding such slideshow to DLNA supported device - more bandwidth saving device could check if something changed and make the steam better optimized. There are a lot of ideas on how to implement such feature, most methods to stream desktop to DLNA using Linux should work when applied to single Android app, so I believe it should be doable.
