Yes, we can do that.

Probably not or if then very slow. X2Go does not handle desktop shell  
that do the rendering server-side very well. With widget toolkits that  
do the rendering on the server (as opposed to pushing X objects over  
the network and leave the rendering to the client) X2Go does not  
perform so well.

Greets,
Mike
