I like the idea with a wiki. In the first iteration people from
different projects that we consider here could first create some short
stubs describing key aspects of their projects (features, assumptions,
requirements, dependencies, etc). Then, in the following iterations we
could try to come up with some readable structure for this.

E.g. I think I could write something like this about Qubes OS to start with:

* Category: Desktop OS (available as installable ISO)
* Goal: reasonably secure multi-domain desktop environment with lots of
mechanisms to make this as seamless experience to the user as possible.
* Main focus on: 1) secure GUI, 2) secure inter-domain interaction
mechanisms, 3) reasonable TCB decomposition (netvm, usbvm, etc) 4)
domain management
* Depends on: Xen, Fedora/Linux (VMs), Xorg
* App compatibility: Most Linux Apps except for such that require
accelerated graphics
* Drivers compatibility: Essentially all supported by Linux kernel
unless they break when run under Xen (some GPU drivers do :/)
* Status: Qubes 1 released, Qubes 2 Beta 1 ISO in the work (with HVM and
specifically Windows VM support, most code in the Git already).
* Non-goals: creating a new microkernel (rather how to best use existing
ones), creating drivers, creating new user apps.
