I'll just skip over the profanity you posted and give you the answer you seem ignorant about for quite a while now:

Yes, it is perfectly possible to start a new ledger independently from the one that OpenCoin started ~1 year ago. In fact, that's even the default(!) mode if you just run rippled with no further switches...
This is also clearly stated in the original announcement from half a year ago.

Your definition of "open source" is by the way not one that is shared by many people and I would recommend to find a different term for that specific requirement of yours ("forkability"?), as "open source" as well as "free software/FLOSS" are actually quite well defined and do not mean what you try to underline with your expletives.
