This area is moving very fast, and time will tell what technologies stay and which disappear, but it's gettint where we can't keep up with it fast enough either.
Sony web-enabled TVs are going to largely use Google TV/Android. See http://www.google.com/tv
for that and the other info, including the box option to using Google TV. Google TV will use Android apps pretty much out of the box, but like the iPad those may not be fully optimized to take advantage of the layout of a TV screen vs. a smartphone screen. They will introduce a new app store for the optimized apps for the TV screen. Details for developers will come out next year according to the above site.
Ford is working on and how now released an SDK for, the Ford Sync system, which will allow app developers to make their apps car-freindly by allowing voice commands to be used, you'll use a regular smartphone, as they found that to develop for what was big three years ago was just not going to work, they needed a frontend to stay up to date, the smartphone was it. After all, Pandora was barely on the radar three years ago, today it has 65 million users, a good chunk of that growth came in the last 18 months. Mormon Channel didn't exist then either. And don't forget all the new features that can and will be introduced to both smartphones and their apps over the next few years too. After all, the car is the 'last frontier' for Internet radio, and over a third of all radio listening is in the car.
TiVo will be another one, I've seen some of what they are doing and it also includes Pandora, and soon eveyrone is going to have Pandora or some other web radio app standard out of the box. So it makes sense to develop for all of them.
Windows 7 Phone comes out just after Thanksgiving. So we finally get a Windows Mobile platform to fully develop Mormon Channel for.
This blog post from the 'Radio and Internet Newsletter, which I've isolated to allow people to go back to it a long time after now, tells a lot of this in stories 1, 2, and 4. The blog has a lot of 'backoffice' stuff about Internet radio, but often has a lot of details about what is going on in the retail marketplace for web radio applications and the hardware that plays them.

Now to content for the Mormon Channel app, the video side is going to need to go back as far as possible on the General Conference and CES Firesides, etc., to make the web TV apps a real value. Other content besides is anything on the Mormon Channel Youtube page, and even this one from FamilySearch: http://www.youtube.com/familysearchvids
Most of what is found on video.lds.org (hope I got that irght) should be in the app as well. If possible any of the material on the Mormon Tabernacle Choir's Youtube page too. They have put up a fair number of things as well.
One audio item is whatever can be cleared from the Church Music site should be on any Mormon Channel app as well, I think that is an item that some have been asking about elsewhere as well.
