Snapstick, watch internet content on TV

Just stumbled across Snapstick on Mozilla-based applications page on Mozilla.org .

Snapstick combines the ease of discovering content on your laptop, tablet, or smartphone with the viewing pleasure of a big screen TV.

Now that sounds really cool. But it still doesn't explain what's the technology behind all this. Digging through the Snapstick.com site, I found the Engadget.com Snapstick review that explained the full details. Perhaps someone at Snapstick is listening, you need to put up relevant content where we geeks can find it easily.
BTW did I mention that this product is powered by Ubuntu. :)
