We are looking for a great commercial or free tool which can monitor all our remote employees and keep the reports centrally. We need it similar to Elance WorkView or oDesk "Team Room", what these tools do is:

• Take screenshots at random interval.
• Track the activity on computer based on key strokes. (not a necessity)

It doesn't necessarily need to track time but will be good to have, our aim is to monitor employees and make sure they're working - that's all.

I'll give oDesk Team Room 10/10 and I haven't been able to find such tool. Is there anyone who can suggest such tool?

Thanks
