Imagine X server technology with compression so tight that GNOME and KDE sessions yield impressive response times when run over modems with SSH encryption. FreeNX is an addition to the remote desktop line with stunning performance. Thin clients use small amounts of bandwidth while handling audio and video, printing, and other heavy applications, and permit the use of session suspension instead of termination. As long as you wish to primarily use Linux, FreeNX provides real virtual KVM switches without hardware.
