I don't do guest podcasts but when we do the V4V Roundtable @nprofile1q... usually uses vdo ninja (I think)

I use a free, open source DAW for lightning thrashes, recorded episodes called Ardour and mixxx for live streams on my own icecast server.

I don't know if this will be helpful to you or not, but if you're ever super bored, I've put some videos together about how I do things.
