I finally was able to finish an .Ogg media plugin for Virtools. Ogg is a fantastic open-source audio compression codec, and a no-brainer replacement for MP3: low-bitrate files sound better, it's license-free (are you paying for that MP3 license? I didn't think so), and it's ubiquitous. There is absolutely zero reason to use MP3 when Ogg is a possibility. Just listen to these compression tests from one of our projects.
Disclaimer: I have absolutely no idea what I'm doing. One of my friends helped out with the core of this plugin, and I fumbled it into a working state from there. I make no guarantees about its robustness. If you do improve upon it, though, please send your updated version back my way.
This goes in your Virtools (or player) Plugins directory:

Here's the [very messy] source:

The above DLL is compiled for Virtools 3.0.
