In his News, Views and a Silicon Valley Diary Dan Gillmor lifts the lid on KnowHow:

The major promise of P2P lies in several simple notions. The first is that we're using only a small part of the value of the devices at the edge of networks. Harnessing their power, from CPU cycles to their ability to create content, will make the Internet universe vastly more valuable for everyone.

In that world, every client -- that is, every PC and other device connected to the Net -- should also be a server. Lots of people are working on this, but a Menlo Park startup called KnowNow has figured out something that just might set off a new Net revolution.

BTW, yesterday KnowNow's web presence was a single holding page that invites people to join them (by e-mailing!) or contact them (by snail mail). This morning (GMT) it was the same. No doubt in the very near future they will do the full monty and announce details to the world.
