MySQL Portable

In my work we have very strict security policies regarding software installation on our desktops. That's a real PITA when you really need to do some experimentation with configuration.
I found over there a way to get a MySQL server running in your system without having to use an installator.
You'll need to get a noinstall version of MySQL. You can find it here: http://dev.mysql.com/downloads/mysql/5.1.html

Then, you have to unpack it. You can do it into a directory like c:\MySQLServer. To start it up, you could use a script like this one:

@echo off

echo Launching mysqld listening on port 3306
bin\mysqld --user=root --datadir=data --port=3306 --basedir=.

This script must be in the same directory in which MySQL is.
Now, you just have to run the script.
I'd really prefer to use some other scripting language like bash, but this is windows...
