Remote desktop and smart card

Hi.

I need to use a smart card while working with remote desktop.

My office pc runs win XP and have a smart card connected. I can not use that card when working remotly, its not found. Like its disconnected.

I also have a smart card connected to my Mac at home. The smart card works fine when the VPN connection ask for my code.

The problem is that it does not get forwarded. I have tried to use MS Remote Desktop for mac and CoRD.

But none of them supports the smart card.

It works fine with parallels/win7 on my mac, I can then use my smart card.

How ever I would like to not use the win/ on my mac.

Do anybody have a soulution to this? Are there any Remote desktop applications that support forwarding of smart card for Mac OS?

Thanx for any tips
