I have to say, I can't recall hearing about Autonomy...not that I keep up with all the tech news, but a $10B valuation is pretty big. Is it just accounting fraud that's going on, or was the technology not what it was claimed to be? $10B for tech that would encroach on what Google/Apple/the NSA would do seems like it would make Autonomy more of a household-tech name, even if it was based in the enterprise sector:
http://en.wikipedia.org/wiki/Autonomy_Corporation > Autonomy's technology attempts to "understand" any form of unstructured information, including text, voice, and video, and based on that understanding perform automatic operations, for example inferring what the user wants and on that basis finding other information that may be of interest.
