Q: What might keep these powerful incumbents from holding back this tide?
A: You've got to have some huge force outside of the United States, where it's getting locked down. What if China says, "The FCC doesn't rule us. We're going to stop assigning frequencies within our borders. We're going to regulate devices so that they play fair with each other, and we're going to open up spectrum." That's going to make the U.S. an economic and technological backwater.
