HyperJohn just gave it a test tonight. There was a lot of buffering, but it was nice to see the lights, dust, bikes, dust, fire and dust while it was up. I was gonna post the link here, but it appears down right now, as well as the link had bmtest in it, so I don't think that'll be the final link.
Keep checking here and I or someone else'll post the link once it comes back up.
Also, it was in irc.freenode.net #burningman that HyperJohn (johng this year, guess he's mellowed) gave the test link. Hop in and join the rest of us unfortunate enough to not be there this year in our misery.
In Dust We Trust
