Does anyone have these files backed up?

I can't find these shows anywhere online.
Specifically, Domain Insight.

I was going to open a new thread asking where to download the old podcasts, and I came across this thread. I downloaded iTunes just to be able to get the Namepros podcasts from the past, but they're no longer there. I read somewhere that iTunes was the only place to get them. Is that true? Can't I get them from anywhere else? Are they no longer available?
