Patches have emerged today that provide support for workspaces with Wayland's Weston compositor and default shell.
Jonas Ådahl published a set of six patches that provide support for workspaces on Wayland/Weston. The patches provide a sample implementation of workspaces for the weston.ini
configuration file, support for moving surfaces between workspaces with the Weston shell, a workspace manager interface, improved focus handling, and other changes needed to make workspaces on the Weston shell a reality.
Those interested in checking out the patches prior to them being merged in the Weston repository can find them on the wayland-devel mailing list
