Multiple Flush Draw Possibilities

[Dopey]

An issue brought up in a hand post in Micro-limits forum is the % of time another flush draw will be out against you flush draw on the flop.

Example:

Hero holds 65 of diamonds on a AQ8 two diamond flop.

What are the odds of another flush draw being out there as well (Only counting a player with two diamonds in their hand, not counting a player with one diamond and a backdoor flush draw.) [Assuming a ten handed game]

I am nowhere near capable of doing the math and a search produced nothing.

Thank You,
