Hold em Odds Question

What are the odds of two players ( or more) completing a flush draw in the same hand at a full table? Where BOTH players are holding suited hole cards and only three cards of the same suit hit the board?

For 2 players given that both players have 2 cards of the same suit the probability is about 3.64%. See your original post for more detail.

So about a 30-1 longshot?
