DEMO is a paid to present conference for 68 companies in 6 minutes present their new companies, products and technologies. The presenters are picked by hand picked by Chris Shipley and a board of experts and they do a pretty good job of bringing all this technology in nice simple to understand forum. All the presentation are available online for viewing and are pretty impressive. I really like Apollo from Adobe , BlingSoftware, TeleFlip and Zink.

As with CES most of the products are now geared toward the Web and Mobility. If you have the time it is definitely worth checking out.
An alternative "free conference" is in the works by Mike Arrington of TechCrunch and Jason Calcanis here are the details so far a few other members of the board are showing up like Robert Scoble:
1. It will be in the San Francisco area.
2. We will have around 250 people at the event.
3. 20 companies will present over two days.
4. The event will take place in the fall.
5. We are looking for a location that can fit 250-500 people. We arehoping we can find a a University that would host the event, or an affordable conference center. Any ideas please let me know.
6. We hope to put together an advisory board of people we really respect to suggest companies.
I would love to see more Unconferences like this spring up in multiple locations like Boston, NewYork, Chicago,Austin,etc, but no so many that it dilutes the content. More like an East and West like VON does.
