Attempt at custom ASIC-Resistant hashing algorithm

I recently forked go-ethereum and replaced the old consensus with a custom CPU-oriented PoW algorithm(AgentHash) as an experiment

What is interesting to me is the implementation/tradeoffs:

• ASIC resistance attempts
• low block-time behavior (5s)
• difficulty adjustment under low-participant conditions
• networking/sync implications in a modified Geth client

Would appreciate comments from people more experienced with Ethereum internals/PoW systems.
