Looks like Dave Zantz has found a hidden web server on Series 2 TiVo boxes. I ran across the article at eHomeUpgrade and it seems like a nifty little hack for all you commercial TiVo owners. Head on over to Dave's website and readup on the howto and get yours rolling now! From the news post at eHomeUpgrade:

Dave Zantz is up to his TiVo hacking tricks again. He informs us that TiVo Series 2 DVRs have a hidden web server integrated into the system that allows remote access to stored video content. Dave says, "it's no Slingbox, but for many people it doesn't require any additional equipment or expense."

I hear the back doors creaking open. :)
