(Sorry for the crude photoshop, where did that hand come from?)
Personally, I think this would be the coolest thing ever. I did some research so here it is.
Using RTT as a template, they used a site called Talk Shoe, a site where the people running the show would call in to a pre-designated phone number, and then be connected and recorded in pretty good quality as opposed to the quality GoogleVoice gets. rybebreadraz could back me up on the details there.
I think a cool agenda could be a review of the last game, introduction to the next opponent, then perhaps an interview with a fellow SB'Nation participant or maybe even a coach or player in rare occasions. So these shows would roughly take up 15 minutes of time, maybe every Wednesday or Thursday, then there's just an HTML widget that could be placed in a sidebar or something.
I think it would be awesome, have I said that before?
