Yep. I use a prime and a Connect. I live in the New York Metro area and get New York local channels via cable. But I'm a Philly sports fan, so I have a db8 antenna up on the roof and it allows me to pick up Philadelphia broadcasts (70 miles away).
I'd love the ability to merge the channels so they're all in one section. I noticed that the latest version of the HDHomeRun Mac application does this already (I'm seeing all my channels in one place from both boxes). It looks like how they handle channel overlap (different channels with same number) is that the cable channel 3 is recognized as just 3. The antenna (Philly) channel 3 is seen as channel 3.1.
I love this app and this feature would make things even better.
On a somewhat unrelated note, I hope you folks have noticed this news story (link below). Basically, it looks like the FCC is going to require the cable and satellite providers to build apps for AppleTV, Roku and any other device which has sold at least 5 million devices. It would seem that it could be a major business opportunity for Channels (to perhaps build the required app for the cable and satellite companies)
That's two years out, at the earliest. But it gives you time to build a business model that takes all this into account.
