A ccminer v0.6 source code release was made, adding myriad-groestl (the table based groestl implementation like in the SPH library) and a jackpotcoin implementation.

jackpotcoin only mines the keccak portion of the JHA hashing algorithm and throws away 7 out of 8 hashes. Still this is way faster than computing the remaining rounds for the hashes that are being thrown away   This is a CUDA coin it seems, and it is fit for solo mining. Quick, the AMD miners are going to catch up soon.
