Razvan talk about hooking Amarok to MySQL database server and create an MP3 file server. I this is an excellent hack:
When it comes to playing music in Linux, Amarok is one of the best audio players out there. It offers almost everything you need, from a clean, intuitive interface to a range of useful scripts. You can even put it on a server and give it a Web interface.
ObsidianMusic was previously known as amaroK Web Frontend. It is a collection of scripts that, combined with a MySQL database and the Amarok player, forms an excellent way of sharing MP3 files over the Internet or a small office network. All the music files in your collection can be played, downloaded, or streamed by a regular Web browser. Furthermore, ObsidianMusic offers search capabilities and music sorting, and can be customized using themes.

MySQL Proxy tutorial
Oreilly has published a nice tutorial using MySQL proxy application:
MySQL Proxy is a lightweight binary application standing between one or more MySQL clients and a server. The clients connect to the Proxy with the usual credentials, instead of connecting to the server. The Proxy acts as man-in-the-middle between client and server.
In its basic form, the Proxy is just a redirector. It gets an empty bucket from the client (a query), takes it to the server, fills the bucket with data, and passes it back to the client.
If that were all, the Proxy would just be useless overhead. There is a little more I haven’t told you yet. The Proxy ships with an embedded Lua interpreter. Using Lua, you can define what to do with a query or a result set before the Proxy passes them along.
