I believe they can address this in future releases as IOS 5 made much of this possible for other applications (apps in the background).
I feel the same. There is a lengthy wish-list for nomad. We do know they have plans for enhancements, but specifics are kept quiet.
What I'd like to see is a nomad iPad HD version that has the menus and other items running in the iPad's resolution framework vs. the subsumed delivery we see now. Speed wise it seems to work well and I'll get my first taste of usability very soon. I would have recorded more on my DVRs if I had purchased this unit sooner - my problem is one of not being around to watch what I record otherwise.
