I think that almost nothing of what I talk about will be a part of Qubes other than preconfigured paravirtualization.... what makes you think they plan to do any of the things I just talked about? Certainly nothing any of the Qubes devs has said led you to this conclusion. If you want an alternative to lookers secure VM you could use pretty much any other thing and come away with better security. If you didn't realize Liberte essentially is an entire system built from scratch. I mean, what makes Liberte different from the system I described other than it lacks a few of the applications I would like to see created. Creating Liberte was not a small task either.
