Hot Recorder is a great application, as I enthused when I first discovered it in May. As a software-based option for recording phone interviews over Skype for use in podcasts, I think it's the best out there.
Two things I noticed with today's install. I have the paid version but had to download it again as I couldn't find the original download. First, the Hot Recorder installer is marked as version 2.0.1, although the app still describes itself as version 2.
Just as well as then I noticed something quite interesting - an option to configure Hot Recorder to work with Google Talk, as this screenshot of the popup menu in the system tray shows.
So you can make and receive Google Talk calls and record those conversations. Not only that, you can also set up a voice mail facility in Hot Recorder that acts as an answering machine for Google Talk and record your own playback greeting. Very useful as Google Talk is currently rather bare bones.
The Hot Recorder Help page has been updated to include commentary about the app's integration with Google Talk (which I guess would explain the 2.0.1 version number).
From what I can tell, this is the first third-party application developed for Google Talk. The first of many, I'd say. Still not a Skype killer, though.
Speaking of Google Talk, Chris Pirillo has some suggestions for what Google should have named their VoIP application. I think GTalk is the best one.
