This is a little embarrassing, but the tool is actually browser-based, powered by Javascript and PHP. I know that's not the ideal foundation, but those were the skills I had at the time. I do have a copy of it online that I used to demo it for a friend.
Being browser-based is not really a problem for me, because I run it on my local dev server and everything is instant. But over the web it has to upload each wav file to the server, which can be slow depending on bandwidth. It does however indicate when uploads are in progress so you can avoid interrupting it.
One of the ways the tool is unsophisticated is that it's designed for a single user. So anyone with the login can see/hear others' recordings, overwrite them, etc.
Anyway, if you're still interested in seeing it, just email me at: alan at [my HN username] dot com. I can send you the URL, username, and password.
A fiend of mine works at an Audio Reading service and they have wanted to improve their volunteer recoding workflow for ages. This sounds like it could have potential for them, and js / php might even be better than alternatives in their case.
