Is OpenSolaris still closely controlled by Sun?
I don't know if Sun still governs OpenSolaris, I know they are very tight as often new technologies are rolled from OpenSolaris to Solaris, but OpenSolaris might have it's own governing body now.
Ha! There are very few non Sun employees involved unless things have changed big time in the last three months.
OpenSolaris is now something you can get paid support for from Sun. There will be a LTS release coming too. I don't think OpenSolaris will go the way Java has gone any time soon. Look how long it took for Java to reach that stage.
