Everything is possible
Select a few files in Finder, right-click on them and put them into a new archive or disk image. Extract files from selected archives to the same, recent, favorite or a location of your choice with one click in Finder. Furthermore, browse archives and disk images using hierarchical contextual menu and extract only particular file from them.
All the above is possible using Springy contextual menu plug-in in Leopard and earlier, or using Services Menu in Snow Leopard. But Springy goes even further. In Leopard, your favorite menu commands are buried deep in "More" submenu. But, not with Springy! Springy contextual menu is back where it belongs, even in Leopard: the root of the menu!
