If you can't meet up try twitter or tumblr. Every day post what you've achieved that day and what you're going to do tomorrow. If you keep it up for a week you'll feel very guilty if you stop. I've got a moleskin notebook that I use for this purpose and it works great.

I'll give that a try. Something more interactive would be nice though if only to generate conversation and set a hard deadline.
