podcast getting programs?

[Karen Lewellen]

Hi folks,
I know here is a more correct name for these, but I cannot think of it 
right now.
In fact I even remember the name of an accessible one, pod racer?
I am wondering if that or any other such program can be incorporated into 
a service like shellworld?
If not, is there a port that might run in dos?
A source from which I used to grab interviews with ease is for some reason 
either ON providing streams, or in podcast form using the feed.
ideas welcome,
Karen
