#2For someone who doesn't know about how the PS3 works at all, could someone explain what the "Master Key" is and what finding it means?

Also, why the discoverer would choose not to publicise it? (Is he planning to sell it??)

There seems to be a lot of high-fiving and back slapping in that thread but I'm also flummoxed as to what this actually means.
I'm going to naively presume it's something to do with being able to run unsigned code on the PS3?

Well the answer to that is on the page. Apparently last time it came out a bunch of people commercialised it by making dongles and selling them, and the scene wants to avoid that happening again before an open source thing is released.
PSGrade (as mentioned in the post) is open source: http://www.ps3exploits.com/2010/11/open-source-downgrade-on-...

A few months ago someone started selling some USB devices that would allow you to install third-party software on the PS3 bypassing the security measures behind sony OS. In short, you could rip games and play them from the hard drive without the disk. Later on, similar open source code was able to achieve the same without buying any special usb device: you could in fact use almost any ARM processor, including an android phone or an arduino. Google psgroove.
Sony of course immediately fought back, first banning the altered OS from the game network and then releasing updates that were not compatible with the loophole. OS on the PS3 cannot be downgraded.
Then, the hackerz fought back and again sold a PSdowngrade device that would allow you to go back to a previous version of the Operative system. Same path, an open source version is released called PSgrade (it's on github) but to work it needs a key associated to your own device or.... a master key.

Can Sony change the master key by pushing a software update? Can they use a different key in newly manufactured units while maintaining backward compatibility?

It's a trusted computing type lock down AFAIK, so not software update-able. I think they can try the latter of your suggestions, but the same process could just be used to discover the new key, or they'd need to do some serious re-engineering.
