I wanted to let you know about a brand new Actual Play podcast! The "Journey to Madness" is a Seattle based role playing group that has recently begun playing Rogue Trader.
The blog is located here: http://roguetrader-40k.blogspot.com/2012/07/introduction.html
Currently 3 sessions are posted, and a new post will be added (roughly) once a week.
In the first 4 sessions the Rogue Trader and his crew investigate and seize control of a Starship deep within the Koronus Expanse (homebrew). Once they return to Footfall they are presented with various endevours, and start by tackling "Vaults of the Forgotton" (from the Edge of the Abyss sourcebook). The plan is to play a few more endevours and then transition into Lure of the Expanse.
Have a listen and I hope you enjoy it!
