I noticed that Rafael Sadowski was working on x2goclient https://github.com/jasperla/openbsd-wip/blob/master/x11/x2goclient/Makefile
Are there any serious technical obstacles to commit the port? Due to the fact that NX is no completely proprietary and close source and in the light of my rather poor experience with FreeNX server I started completely switching to X2Go.
