Think on the EFF ./. AT&T/NSA issue, after google'ing i found a firm in cologne/germany who presents NARUS products like cool-nice-to-have cars: "...Diese Lösung analysiert große Datenmengen bei hohen Übertragungsgeschwindigkeiten bis zu OC192 in Echtzeit und schafft so mehr Transparenz..." http://www.modcomp.de/index.php?option=com_content&task=view&id=52&Itemid=55 (Translation: "...This solution analyses large data/traffic amounts at high speed rates up to OC192 in realtime and puts more transparency...") Transparency... I really do not know, if it can do MITM stuff and if my ISP has such a box already... And what is meant by "...Business Intelligence..." on that page?
