I wrote both of these with input from the community recently, so they should 
be fairly reliable and up-to-date - was there something missing that you 
noticed? Suggestions welcome.

There are several different UIs available. OE-core provides Sato (mainly for 
testing); the meta-openembedded repository contains several layers that 
provide some more (GNOME, XFCE, etc.)

As Denys mentioned this sort of thing is (or is expected to be) provided by 
multiple OSVs.

I would imagine they would take the place of the commercial layer - after all, 
both would be providing the same sorts of "policy" type metadata.

It looks good, but I'm not sure that you'd expect to be mixing all of these 
layers together in one configuration; e.g. the commercial layer / distro 
layers.
