Windows Live Mesh gives you the ability to store up to 5GB for free on a centralized storage area on the Internet. Once you setup your account you don't have to load any software to be able to access your data from any machine. All you need is a browser and an Internet connection.

Windows Live Mesh is still in beta but it seems to working pretty well. It will interesting to see where Microsoft takes this capability. The basic concept is the ability to load a small application on your computer, and link it to your Live Mesh account. Anything that you drag into the folders of the account gets shared to all of the systems that are part of your Mesh Network. This allows you to synchronize information with your business workstation with your home workstation without having to drag the files back and forth or emailing them to different email accounts.

Just install the live mesh software on each device.  Then add folders to your mesh.  Your forceful than be automatically synchronized and always available for all the systems you have set up on the mesh.  You'll also get access to the machine remotely and init programs on that machine the matter where you are.

It is all so simple to share files and photos with friends and family and colleagues.  Simply invite them to a folder.  Everyone has kept up to date because files can be synchronized automatically with all of your devices in all of their devices. To take a tour of this product click here. Enjoy!
