Biggest question I have been getting "Is Monty happy". The short answer is yes, Kaj has written up a longer response here:

My quick thoughts? I think it is pretty exciting. I think that it is good for both companies. We have good open source DNA, and they have good DNA. Many people forget now, but Sun really was the first company that we, the UNIX community, could trust with open source. Ignore the complaints you see, Sun really has been moving in the area of open source longer then anyone.
MySQL is open source and will stay that way. Neither Monty nor I would be happy if that was not the case.
Is Sun giving up PostgreSQL? I got a nice letter from Josh Berkus welcoming us into the company, so I really doubt that :)
I'll post more later, but I am excited.
(Oh, and yes I wanted it on Slashdot first: http://developers.slashdot.org/article.pl?sid=08/01/16/135243)
