If there was such a fee, nobody would use your exchange.
That's the beauty of this whole thing. The users self-select exchanges that are insecure because they're easy.

Vircurex does charge a withdrawal fee.
Wow. Sorry, then: that's just indefensible.
Exchanges usually charge a withdrawal fee to cover transaction fees. BTC-e also charge a fee for example. Bitcoin software doesn't provide (an easy if possible at all) means to compute the fee up front to pass on to the receiver. So exchanges charge a fee that to cover the average cost per transaction.
It's fucking amateur hour here.
