mBS Equinox is purely based on Equinox and is geared to embedded use.
It contains all the compendium services but no other frameworks.
ModuleFusion is a distribution geared to enterprise use and can be
used with Equinox and Felix. The content is driven by enterprise
requirements. Therefore, the compendium services included are the ones
which are useful for enterprise use cases. Additionally, frameworks
like Wicket, Hibernate & Co are included.
