Single small button/key for ejecting disks?

[drewcare]

I'm thinking about using a mini as a HTPC (if they ever update the thing...), and I was just thinking about ejecting DVD/CDs... since the mini itself doesn't have any eject button I was thinking about a small device that could sit next to the mini with the sole purpose of performing an eject. The Griffin PowerMate looks like exactly what I need, but its expensive, and quite overkill. Has anyone heard of anything like this?

I'm also willing to look into hacking up a keyboard and just providing one key to push...

Are there any existing projects/existing products that do what I describe?

take a look at remote buddy (http://www.iospirit.com/).

you can map the buttons on the apple remote to any program (one of the default actions is disk eject)

you can also use a wii-mote (connects via bluetooth). I hacked together a "sensor bar" from a couple LEDs, a resistor and an old USB cable, so now i can use it as a mouse.
the range is good enough to use as a remote from anywhere in my apartment.

I'm more interested in a physical button that can be located near the mini and can eject the disk. I plan on replacing a DVD player with the mini, and for ease of use for my wife I'd like to have some sort of eject button...

After thinking a bit, I might just go for a USB numeric keypad. It should be small enough to sit next to the mini, and I'm pretty sure I can re-map keys to eject via system preferences. Any suggestions as to a keypad?

I think a usb mouse with an extra button should be able to do this. Might be abit cheaper than buying a num pad.
