I've tried this out and it is dramatically better then other alternatives, full screen-sharing suffers from latency issues (screenhero, logmein, etc...) and sharing an ssh session is a pain to get setup (e.g. wemux). I highly recommend it.

I really really like this project.. combined with some HTML output page of some sort, one can display errors in real time to an interested party for debugging purposes.
