Q: What OS is it?
Q: When will it be available?
Q: What customizations will it have?
A: See first post of the real "XDA Live" thread: http://forum.xda-developers.com/showthread.php?t=294809
Q: Is it from provider "X"?
A: No, it's from multiple ones, and you cannot be told which ones.
Q: Why isn't it released yet?
A: Because all identifying information in the ROM must be found and eliminated, otherwise kyphur's source may be fired from his/her job or worse. Does NDA mean anything to you?
That's all I can think of so far.
