Soooo I forked it, accepted that 300 mined blocks and diff =4 ;]
My 3 P2pool nodes are running on https://github.com/Rav3nPL/dubstepcoin/tree/patch-1 daemon that have killed #5 checkpoint.
If there are some ppl that want to waste some power (dev will probably restart chain... or no?) ure welcome to mine
I`ll mine it for day or so just to check it is all ok (I`m not 100% sure that my P2pool fork will find valid blocks ;])
