This week's Demo conference (brought to you by Network World's Seminars & Events group) will feature brand-new technology offerings from 67 companies. Among them are some pretty cool tools - and we got a sneak peek at some of the products being launched this week in Arizona.

DataPod is an Israeli company that will show off software that lets your data "follow you around." The software aims to solve the problem of users who have their data scattered on several PCs and the problem of multiple people trying to access the same file.

Users install client-side software (called DataPod) on any PC to which they want to have access. Data stored in the user-defined folder is automatically synchronized with the other PC where DataPod is installed. A local copy of the data is stored on both PCs. When changes are made to the file at one location, they are sent to the other system. On the sharing side, co-workers can access one copy of the same file without having to send the file back and forth through e-mail, because both workers will have the file locally, and changes will be updated automatically.

The updates are sent over Secure Sockets Layer, and no third-party servers are needed to store data (as in some collaboration-style software). It's also a bit different from some remote access offerings (such as GoToMyPC), as only the data is being accessed, not the actual computer.

The company plans to launch the product next month, with trial versions of the software available. DataPod plans to offer monthly and yearly subscription plans, and a direct-purchase (lifetime subscription) offering. Click here for more details.

SightSpeed, which makes an awesome desktop videoconferencing application, will debut its SightSpeed Video Messenger Multipoint service, which lets up to four people have a videoconference from PCs. The same technology that makes SightSpeed's peer-to-peer-based Video Messenger attain such low latency will be applied to the Multipoint offering, with the only difference being that a separate server (hosted by SightSpeed and placed around the world in different locations) will aggregate all the video and audio streams. Much like an audio-conferencing bridge lets people from different locations talk on the phone, the SightSpeed service does this with video. People who don't have a Web camera can use the service by viewing other participants through a Web client.
