Sorry for the giant post, but there's too much to reply to here...
Making a new coin and leaving CLAM rules unchanged does seem the fairest way to proceed. Then the people who didn't hear about CLAM yet will still have CLAM waiting for them when they finally do hear about it.
Maybe as BAC suggested we should take any discussion of "doogcoin" off this thread, like how discussion of "Bitcoin XT" was moved away from BTC forums - since it really isn't anything to do with CLAM, other than using a snapshot of the CLAM blockchain for its initial distribution.
I took a snapshot of the JD database just as CLAM block 730000 was staked. As the first multiple of 10k after the idea was proposed this seems as good a point as any. Having the snapshot point be in the past prevents any manipulation by people buying CLAM just to increase their initial allocation of "doogcoin". I checked the Poloniex charts and it appears there was no unusual trading before that point.
I know this is kind of off the table for now, I am just curious how quickly you could implement this if you found the need?
