That was just a preliminary step, although the followups did discuss it.
When the immediate uses work is done, they will always be available and
automatically kept up to date.

I have most of the code working, there are just various bits of
infrastructure that needs to be changed in order to make it work
properly all the time, and its a bit intrusive. Its not vaporware, it is
really coming... There are just a couple of more steps along the way :-)
