If you were closed out of Microsoft’s Live Mesh preview for lack of an invite, you now can get in.
Microsoft has opened up availability of its Live Mesh Software + Service sync/collaboration platform to any U.S.-based tester with a Windows Live ID. (Those outside the U.S. also can get access to the test build as long as they have a Live ID and are willing to change their Windows operating system region and language setting to EN-US.)
