Ah, ok, the 'pulling the wool over the eyes' school of copy protection. It suffices for impressing clients, but offers no actual security at all in practice. There were calls for that sort of thing in SVG, but we declined because it gives the appearance of solving a problem without actually doing anything. In addition, it compromises accessibility to not be able to select text. Would the text be barred from being indexed, too? Would it not show up in search engines? -- Chris mailto:chris@w3.org
