I don't believe that Tycho would do this, but having such a large pool and still growing is getting scarry, especially since it is rapidly approaching that fearful 51% scarey.
Actually there is still a VERY long way to 50% considering that deepbit is not the only pool that grows rapidly.
I am not sure that I agree; especially with people offering to bring GH/s hardware online with your pool. I think you hit nearly 40% today, although we know much of that could be due to variance, however the pool hash rate has grown massively in just the last week and only slush competes significantly and he doesn't appear to have the time or resources to take his pool to the next level. Perhaps many small pools or a couple growing medium size pools (relatively) would help alleviate the apprehension.
