Have you tried the new FreeRDP client yet?
I've not done any extensive testing but it does now support both Microsoft's RemoteFX & RemoteApp services. Its an Apache
license app and v1.0 was released and demo'd at the Ubuntu Developer conference in Nov 2011.
RemoteFX - https://github.com/FreeRDP/FreeRDP/wiki/RemoteFX
and
RemoteApp services - https://github.com/FreeRDP/FreeRDP/wiki/RemoteApp
I've configured Windows 2008 r2 servers on KVM and on AWS EC2, published applications for RemoteApp and then from linux/ubuntu
machines run the xfreerdp client and the Windows RemoteApp appears on screen like any other app. I used to have to use
seamlessrdp for this but now it just works since the freerdp v1.x release.
I'd like to see FreeRDP support in x2go as I understand in the next Ubuntu FreeRDP is replacing rdesktop.
