Regarding the VNC point in your post, I’ve experimented with this a whole lot in recent times getting a good remote desktop solution going. TigerVNC server, using its embedded X server, plus the TigerVNC viewer, work absolutely perfectly. Even including the viewer supporting proper dual head, resizing, switching and all. Of course, if you want to use your existing X server it might not work as well, I haven’t tried it. For most of the rest of your complaints, I use web apps for everything, even on OS X / Windows. Sad at the state of native apps on both Windows and Linux.
