Plastic SCM supports "stashing" / "shelving" changes, and it implements a combination of what Git and Perforce / TFS can do, as you can find here: http://codicesoftware.blogspot.com/2012/02/shelving-stashing -introduced.html
Plastic SCM can:

- Keep a cache on the server - for example, TFS and unlike Git
