There’s a nice panel applet for Gnome named gnome-globalmenu, that give you title bar behavior similar to OS X.  Unfortunately, it seems to calculate the application name for the menu by scanning your main menu, looking at run commands, so it displays the title "CD/DVD Burner" instead of "Nautilus" or "File Browser" when a Nautilus window is activated.

The work-around is to right-click on your main menu, and edit the menus, and change the command executed by the CD/DVD Burner accessory to be "gvfs-open burn:/// ".

Then you have to logout and login.
