Can I install JVB 2.0 From quick-install

1,Can I install JVB 2.0 from quick-install or manual ?

2, When I share my full screen(1280x1024) , other person watch it on another PC with a 800x600 display resolution, the font is not clear . But we share a 800x600 screen and watch it with 1280x1024 monitor, it has some improvement .
Do you have some suggestion for this? can it automatic regulating ?

You can do that at the moment with slight changes of the quick install guide: Videobridge many warnings and errors in local server
