Actual transparency, not just words? That could be free access to their internal architecture (not exactly likely), or more plausible, external, independent auditors. However, I think you're focusing on the wrong party here - I think it's a lot more reasonable to request this of the government than of companies. There's no reason not to require the government to publish the general structure of what they're doing in great detail, and to let others make up their own mind if it's overstepping its bounds. In short: I want an independent parties to have free access and be allowed to verify what's going on.
