I think your Archive Mounter in your link is exactly what I'm looking for, but I couldn't find it on Debian.
I found another solution: http://techthrob.com/2009/03/02/howto-add-items-to-the-right-click-menu-in-nautilus/ which is quite good but I still wish I could move up my custom action to the top. Best regards, Hoang Le
