I agree on shutting down the games till things 'normalize'. No point in assuming unnecessary risk. 

Be it nonthreatening or accidental it still is sort of a big deal that there is a pool that could 51% the network. I was under the impression that that was one of the key reasons to merge mine.

Would a solution to how many alternate algos to consider consist of looking at the amount of hash they contain, picking those that could offset a certain % of the sha power? Would that be enough to keep a 51% attack from taking place?

If we did 3 different algos and were able to make it so each one was 33% of the hashing power would that be a potential solution?

How exactly would the other algos work to keep the network secure? Is there parity needed between the speeds? Like ant miners mined at 1 g/hs and scrypt miners were 1 m/hs, how would that impact miners here? Would the alternate algo networks be that much weaker to the point of it being a drop in the bucket ? I have been out of the mining loop for a long while now so i could be waaay off base with my thoughts here.
