I heard about HotRecorder thanks to Robert’s post. Basically, you may record Skype and Google Talk conversations and save them to a file. Perhaps that’s an interesting add-on to create new PodCasts?

Certainly, the tool HotRecorder is able to do this, however they seemingly allow this only for users of the premium version:

Due to the great demand by HotRecorder users to convert the recorded .ELP
files to .wav or .ogg, we have recently released a beta version of the audio
converter for HotRecorder Premium.

So far, HotRecorder meets my expecations of being a program for backuping your important conversations – in case one needs to do that. However, due to the lack of openness from the company to people who simply cannot (or do not want to) afford $14.95 for the premium version, they’ll probably get some bad karma for skipping on us poor students! :(
