San Jose based company Pramati announced Dekoh today and gave me a look around the application. Dekoh's goal is to bring the web and the desktop together and to give developers the ability to create applications on top of that platform. Those applications can be shared and deployed anywhere in the network. It's a lofty goal, and with more flexible desktop technologies on the horizon like Apollo and WPF and some more entrenched properties like eyeOS and YouOS that could do the same thing, I'm not sure it will stack up. (Richard MacManus covers a lot of WebOS properties on Read/Write Web)
That said, there are definitely parts of Dekoh that don't exist in other places. Dekoh is built on Java and you can move seamlessly between online and offline mode thanks to an embedded web server. I asked about security and Vijay Puller, the CTO told me that they had configured the port so that only the local machine could browse to it. When you create an account, you're given a Dekoh portal, something like yourname.dekoh.net and you can add buddies, install applications and share your desktop. It adds an interesting twist of social networking to the webtop space and in the example I saw, you could share photos or invite your buddies to play a game.
In the end Dekoh is trying to cover a lot of ground by incorporating Widgets, the webtop, online/offline access and home brewed applications. The ideal solution needs all of these to succeed, but I'm inclined to think the more free form solutions that exist are going to ultimately succeed. But throw some productivity applications into Dekoh and you could have a great intranet portal that works whether your at the office or on an airplane. It's all just a matter of getting the developers to come to the platform. They've set up a developer portal at dekoh.org to help with that. The company has been in business since 1998 and profitable the last 3 years.
