We are working on it and hopefully we can offer it in a year or two. There were enough changes this year with the chip timing system that we did not want to pile yet another thing on top of it.
The big issue is that internet connectivity from the summit is hit or miss. The only internet we have up there is via a USB based 3G modem. We are right on the fringes of connectivity, so bandwidth is rather limited and even a 100Kbps video stream would kill it.
The PPM finish would be a bit easier but we still have a potential bandwidth issue if we had to use a 3G based connection.
We try to post live results to the website every 5 minutes or so, thus you can watch folks that way and know where they were last seen. But in the case of the results posted from the summit, as soon as a storm rolls in we tend to loose that link.
