The guy who made the first blue LED won a 1.3 million dollar prize. I'm assuming the reason BU is able to collect royalties is that their method is the one that's being used commercially. Look at the description in wikipedia: Does p-doping Indium Galium Nitride seem like a trivial process?
Making the LEDs blue is actually a non-trivial bit of engineering. The patent isn't about LEDs being blue, it's the engineering behind making them blue. This is a totally valid thing to patent, just like the hybrid engine patents Toyota has.
This is the way the patent system is supposed to work. The university creates a useful product based on a real technology advance, patents the idea, and then when it becomes ubiquitous the university is able to calculate the worth of the technology and gets large firms to license appropriately. This is completely different from software patents where it's mostly "I did it first, haha."
There's a RFC about one group's experience with using IPv6 and NAT64 exclusively (not dual stack): https://tools.ietf.org/html/rfc6586 It looks like the biggest stumbling blocks are chat clients and games. The result is not too surprising, because most P2P networking arrangements involve some kind of passing of IP addresses around, and it's doubtful that most programmers would have put in IPv6 support already.
igrigorik writes "In the short span of just a couple of years, the Ruby VM space has evolved to more than just a handful of choices: MRI, JRuby, IronRuby, MacRuby, Rubinius, MagLev, REE and BlueRuby. Four of these VMs will hit 1.0 status in the upcoming year and will open up entirely new possibilities for the language — Mac apps via MacRuby, Ruby in the browser via Silverlight, object persistence via Smalltalk VM, and so forth. This article takes a detailed look at the past year, the progress of each project, and where the community is heading. It's an exciting time to be a Rubyist."

It is one of the most popular addons for firefox, and in my opinion among the most innovative. It brings a coverflow-like 3D interface to the web. Just another example of what ISVs can do building on open source software."
