Wow, after hearing that Acacia has anything to do with this, I am not surprised at all. I worked in the distance education department for a University a few years back. At that time, they were making rounds among the education industry, and sending letters asking for several hundred thousand dollars, or 5% of all profits made from a series of patents.
The patents? "A system of distributing video and/or audio information employs digital signal processing to achieve high rates of data compression" over cable, tv, telephone, and as they were implying, the internet. Their claim was that anyone streaming video or sound needed to pay up. I mean, honestly, transferring compressed data over a medium!? And of course they didn't go after larger University's that flat out told them they wouldn't pay...
Acacia is one of those companies at the bottom of the barrel. Even worse than SCO, because their whole business is suing over patents, like NTP.
