What is the deal with the pools for Naut? The net hashrate shows over 550 MH/s, yet most of the pools in the OP are dead and the two working pools I can find ( 0free mentioned in OP and IPOMiners, which is not mentioned) only total about 50 MH/s and so it takes them 24-48 hours to find a block. 

Seems like there is a huge pool that is happily raking in huge amounts of Nautilus while effectively blocking anyone outside of that stealth pool from being able to mine more than scraps. Maybe I'm paranoid, but I don't see this sort of thing happening with most coins which makes me wonder, considering Naut's links to the old status quo (Wall Street).
