I've been looking for a solid way to have a full backup of any podcast recording I do, and SkypeCap might be just the thing:
SkypeCap records audio conversations you have using the Skype Voice over IP (VoIP) service to MP4 audio file. You can save sessions for later use and playback
It's OS X software, which is what I need. Right now, I record my end of the call, and Michael records his - and then I mix it all together at the end. If Audacity crashes though, I have a mess (and that happened to me a few weeks back). I might have to give this a look.
