* Encircle all packaging related stuff within sugar in one well designed packaging system, 0sugar:

** move packaging related code from glucose to 0sugar e.g. if there are two activity installations, one to /usr and one to ~/Activities, sugar decides what version is preferable, or what should happen if user removes activity. This is regular packaging work which should be moved to packaging system.

** extensive usage of centralized (native packaging systems like rpm or deb) and decentralized (0install) models

** patch 0install to support not read only usage of installed packages (some activities could be under development)

# sugar part, collect all packaging related code in packaging core (could be dbus service) i.e. sugar shell will just ask packaging core to get list of all activities in the system (installed from native packages, via 0install, just placed to ~/Activities) or to launch particular activity by its id (packaging core will check what dependencies should be installed/downloaded and what sources to use, native packages or 0install)
