[X2Go-Dev] USB forwarding? (esp. @Alex & @Mike)

Hi Devs (esp. Alex and Mike),

this topic has popped up before, but it seems no one is really tackling this (or did I just miss the relevant posts?):

Forwarding of USB devices from the guest to the host.

Our commercial competitors offer solutions to forward, say, a USB card reader to the host, so digital signatures can be performed on a (windows) terminal server.

How hard would it be to add this feature to X2Go (especially when working with a Windows client)? Is it a difficult task, or simply a matter of "nobody got around to coding this yet"?
