Hi, it's not 100% in the topic but... i found an article about cpu detection, and a library named libxpl. It run on linux and Windows, and could probably easily ported on intel mac. http://www.arsoft-online.com/index.php?option=com_content&task=view&id=17#libxpl I don't know about the licencing, the wiki page about the licence is blank *sigh* -- kerunix Flan
