I read the Simoleon Token code and it looks quite similar. That token looks like a subcase of the ERC 891 proposal on which CehhCoin is based. The balances aren't actually ghost, since they are transferable. The only difference is that the first time you transfer from a specific address, the call will be a little bit more expensive because it also needs to mark the address as mined. SIM token will have a cutoff amount, unlike CehhCoin. The balances aren't fake because they won't suddenly disappear. Also, unlike SIM, CehhCoin aims to have a miner. All addresses have the same amount of SIM, so there is no mining incentive. CehhCoin amounts depend on the address itself, so there is an incentive to mine.
