I came to this forum for the cigar chat but I just realized something I hadn't before. I do an accasional live streaming broacast which I archive and then put up as a podcast afterwards. Reading some of these posts made me realize that I could use skype as an audio source and have somebody call me on there and then broadcast it. Well the annoying thing was that with nicecast (the program I use to broadcast) you have to select a source and then use effect filters, which is what I used to do my voiceovers when I play music. I did some hunting for a way to use skype as an audio source and play itunes music and discovered the program allows you to capture audio from any app so basically now I can do a music broadcast, voiceover, and have guests call with skype and have them on live.
The way I am doing my podcast is through a php script I found which just takes any audio files you dump into the directory and sticks them into the podcast feed. If you need any input on any of this stuff, let me know!
