Interesting concept, however with the little info provided here, I don't see:
-how you plan to make it pool resistant (why wouldn't they be able to spread the reward?),
-what stops someone with a 1THs asic from mining this... I don't see why it wouldn't work in http...
- SevenCoin it's pool resistant because the block reward it's one satoshi. They cannot pay shares and they cannot earn nothing if they will pay who find the block, because satoshi is the most little amount, and I've remove all tx fees.
- Try to config a big ASIC for work in SOLO with getwork protocol and you will see that don't work, or you lost 90% of your hash power. It is, they work fine only with stratum protocol.
