I really want a portable keyboard that I can type on quickly while walking around, but I don't think these guys have anything like a product. This looks like an empty web page to measure interest.
That's what I'm hunting for as well; have been for the past few days. Something like BlueTwiddler ( http://hewner.com/programming/ ) is pretty much perfect for me, but it was never commercialized. I'm thinking about picking up http://theperegrine.com/ , adding Bluetooth support, and turning it into essentially a chording keyboard for wearable computers. I need something that will let me type on Glass, the Epson Moverio, and my phone with ease. I'm hoping in the next year that I'll be able to ditch non-wearable computers, from an interface perspective (I'll still have them for heavy lifting, of course).
The Peregrine looks to be the most promising platform for this kind of input. The only limitation I've seen is you need the finger dexterity of a guitar player to quickly and accurately type that way. Then again, the only other solution I've seen is the four button spiffchorder[0] and a trackball in the other hand. I don't like those only because you can't do anything else with your hands while you're using them.
From what it looks like, the founders didn't submit it to HN. For all we know, this page was thrown together as somewhere they can direct people who ask them what they are working on, not somewhere they are actively trying to drum up interest with (if they had nothing beyond what the page shows, my guess is they would have gone with a Kickstarter, rather than just an email capture).
