There are some pretty obvious but unaddressed issues with XMR. If they do not adress them, I can't see this ever being a success.

A DSS dish sits stationary with a clear view of its satellite at your house. A car is not stationary. What happens when you go under a bridge? A tunnel? Under an overpass? Though thick overhanging trees? In parking garages, etc. You see where I'm going, I hope. :) Those with DSS know that electrical storms can cause erratic reception. Same with XMR.

These are just the obvious issues, but I wouldn't plan on XMR going anywhere very soon. *shrug*
