Is this company ok with this being posted? If so, they should say what company they are, because being associated with a clever puzzle like this is great for recruiting (even if it's not being used anymore).

If not, they should probably take it down, as having the solutions posted would ruin the evaluative value of what must have taken a very long time to make.
