Can I use a webcam on a C90 thin client in a RD session without Citrix?

Can I use a webcam on a C90 thin client in a RD session without Citrix?

My object is to let our Windows Remote Desktop Server / Wyse C90 users participate in GoToMeeting HDFaces meetings.

My Googling seems to indicate that we need to buy Citrix XenApp to accomplish this, at about $945 for every five users.

I just wanted to see if we need to buy the Citrix to get it done or if the C90 can recognize and use a webcam all by itself.

We are using LogiTech C260 webcams.

Thanks!
