Windows Live Folders Beta Open
The Windows Live Folders team has opened its beta for new testers. 
I have been looking around and immediately I am taken aback by what seems like the requirement to upload your files one-by-one! As I browse around I see no options to upload a directory or folder's worth of files. This definitely needs addressing pronto Live Folders team. 
PS Raise the quota while you are at it. 500 MB is pitiful. I am prepared to pay. You also get the ability to create folders in which to organize your content.
I am curious to investigate further and see if the FolderShare client and sync functionality will be integrated or remain a separate offering. There is a component to allow the private and public sharing of folders and you are shown the URL of your content as it applies to the various folders.
