Regarding high volume production and how inexpensive the receiver could eventually become:
I can offer a point of reference in the market for DVB-S set top boxes. The following discusses an Android-based DVB-S set top box with integrated wifi.
They are available for about $100. Unfortunately, they are not available in the US, unless we were to import them, which we are seriously considering. The thing that is holding us back is that we are not able to gain access to the firmware, which would ensure that our software could be installed on the boxes. Eventually, we hope to have an Android app that can be used by any of these boxes, but for now, we're concentrating on Linux.
If we were to put an order in for about 5000 units, we could receive a discounted price and also have access to the source code to make certain that we can do what we want to do.
But this particular type of STB might be a bit fancier what we need. It's actually possible to do what we need to do with just a cheap wifi router and a DVB-S tuner. Once we do that and start production around 10,000 units, we should be able to get the price to about $75.
If we were able to put in a production order for 50,000 units, then I'm confident we could get to the $50 level, with a good chance of being even less. A production run of one million units is a completely different story, but that's when we can start talking about a $25 O-Rx.
At $25, we could figure out all kinds of ways to be creative with distribution. Maybe even a promotion with Firefox for their new smartphones.
