I wouldn't expect much here. I don't see a lucrative early-adopter market. The wealthy and privileged are already mostly exempt from police states; their biggest victims are those with the least money and power. There also isn't a big, obvious revenue stream to divert, as with most startup disruption.

The one bright spot here I see is Twitter (and the parts of Facebook that are most Twitter-like). Turning everbody into a micropublisher and microeditor has helped make police abuse much more visible.
