Well, it is not only for updating issue (this system might be useful for
centralized deployments only as a central place for keeping information
about all sugar projects and as a build farm, in both cases it will be useless
for dextrose since it has chosen another way) but more about doers'
environment [1] which also based on regular (ie ditro) instruments
like yum/apt :)

If I got it right, it is all about fetching updates on dextrose user
side? i.e., coding non-visual and visual components for sugar shell?
