All of my data files already existing under one folder tree on my hard drive. I want to:
* Be able to select subsets of folders and/or files within that local folder tree to synchronize with Skydrive.
* Be able to select subsets of folders and/or files to share with other people via Skydrive.

I do NOT want to create duplicate copies of files or folders on my local hard drive (because that wastes space and is hard to keep all versions current).

CHALLENGES:
* I believe Skydrive defaults to creating an additional "Skydrive" folder into which you can copy files which will then get synched to the cloud.  However, Doesn't this create duplicate (forked) copies on your hard drive?

* I believe the only way to share with others is to do so via browser, via shared folders, but am not 100% sure about that.
