Finally, Microsoft have finally retired FolderShare and replaced it with Windows Live Sync. I've only just started using it, and so far it looks the exact same as FolderShare, which is definitely a good thing. They've also added Unicode filename support, the lack of which was for me the biggest drawback in using FolderShare. I just hope Microsoft intend to actually improve this amazing tool, since it hasn't seen any visible improvement in over two years. To be blunt, the Microsoft treatment of FolderShare so far hasn't been very impressive, as is evidenced by the FAQ posted on the Sync team blog:
Q. What will happen to my computers running FolderShare? What about my folders and files?
A. Sync is designed to make the transition easy for you. When Sync releases, any computers running FolderShare will stop synchronizing files [emphasis mine --TG] and will notify you that you need to download Sync. All of your files and folders will remain untouched on your computers, but you need to install Sync on each computer to continue synchronizing files.
