Part of the reason this is possible for us is because the National Weather Service currently provides a free feed of raw (Level 2) radar data from their NEXRAD network (https://registry.opendata.aws/noaa-nexrad/).

Assuming other national data feeds could be acquired and decoded at a fairly low cost, then other feeds could theoretically be added.

I suppose whether or not this project is successful is probably the determining factor in our case.

I know that some Motorola devices don't support Live Wallpapers. I'm guessing that's the problem because otherwise the permissions we use are pretty basic (coarse location, network access).
