Microsoft's Windows Live Mesh has a relationship with SkyDrive, too. Windows Live Mesh is a peer-to-peer sharing service that lets you designate hard (or solid-state drive) drive folders on your PC or Mac for sharing over the cloud. Here's the interesting part: folders also can be synced between a local drive and SkyDrive. Up to 5GB of SkyDrive's 25GB cloud storage quota can be used for this Windows Live Mesh cloud sync--which works in a way similar to Dropbox. However, it is limited to using the free native apps for Windows or Mac OS X and desktop browsers. Neither the Windows Phone nor the iPhone SkyDrive apps can see or use Windows Live Mesh folders synced with SkyDrive.
