I take up assignments on odesk and I like this very much. In my experience the screenshots are only reviewed when the work expectations are not met - I don't think anybody looked at those in most of the work I have done so far (apart from the first couple of days).

Just the fact that they exits promotes transparency and fosters more trust.

Occasionally when a task I estimated to take 30 minutes takes 3 hours I don't have to offer an explanation.

The tool also automatically tracks time that I spend working on a project, submits time sheet / invoice at end of the week ...
