I use Acrobat.com to store client files so I can access them when I'm on the road. I use a laptop for road work and a desktop when I'm in the office, but keeping track of new and updated documents between multiple storage points quickly becomes difficult.

Having an offline/on-line sync feature with options to sync by filename, date/time, file-type and others would be such a time saver and would prevent version over-writes. I'm not sure exactly how it would work, but perhaps allowing a user to create one or more profiles - each profile describing the hardware and the root of the sync'd folder - may allow for multiple sources to be managed.

In theory, an Acrobat file space may contain many files tagged and bagged with source file paths from all over a local file system, so any method of sync would be a major time-saver.

In the same thought space, uploading and downloading of multiple files would be great too.
