The main advantage of using a mask like that is once applied, you can change the background color/pattern etc, and not have to mess with the text's gradient. The text's mirrored effect is totally independent of what it sits on. This is powerful as you move/edit your text or background.
The program I used is called iShowU

Looks great! What is the main difference in using a mask versus applying a gradient direct to the mirrored text?
And what product did you use to capture the screencast? I have a project that will require this.
