Is not forwarding the transaction really that much of a protection.  Presumably, a double spender would have direct connections to miners.

You could reduce the risk of double-spend attempts by actively distributing/resending the received transaction to as many nodes as possible. This makes it hard for the attacker to have success with a double-spend transaction as most clients should already know the first tx.
But this will not help on all attack vectors.

I think a "green address" could be what you are looking for: https://en.bitcoin.it/wiki/Green_address (which AFAICT is limited to usage on Gox).

Is there any accepted method of securing a payment without waiting for confirmations?  Is there a certain amount of time one could weight before crediting someone's account with Bitcoins (received through the network without confirmations) that would lower the risk of a double spend?
