Systm episode 4 is out and it's all about podcasting, including a look at the TWiT setup. I haven't seen it yet, but Bittorrent is busy doing it's thing.
On another note, I was surprised that this wasn't on digg.com yet, and got quite excited about being the first to submit it (yeah, like that was ever gonna happen!). When I tried, I got an error (screen grab below) - looks like someone has reported revision3.com as being a bit dodgy on digg.com.
