For example, you can start/stop redstore from DBus service with pointing
it ~/.sugar/PROFILE directory.

The idea is making theis switch as easy as possible for users, e.g.,
check-box from Control Panel. The way how it might be done is setting
XDG_DATA_DIRS environment variable that points to new directory with
dbus-1/services/*.service files (it is how Sugar Shell from Sweets
Distribution runs sugar-datastore from /opt directrory), i.e., there is
no need in deleting original sugar-datastore.

Also, Sweets Distribution has Sugar Shell plugins in form of arbitrary
code in jarabe/plugins/ directory. If you think it is useful to have
SemanticXO plugin (w/ Control Panel component), plugins system might be
tweaked to handle things like setting environment variables.
