Trying https://www.focusmate.com, with good results so far.

In this weeks Hacker Newsletter (448) I saw an article about letting others watch you work.

focusmate.com is a free service to pair with a stranger via video chat to get your work done, separately, together. Book a session on the calendar, join the video, communicate your goals verbally, then knuckle down.

The mind boggles, but it worked for my first session. I’ll be trying it again soon.
