But if they are different implementations they should not use the
same namespace... (see below)

It was not my intention to seperate interface from implementation, but it is
not correct that two implementations use the same namespace... This violates
the "hierarchical package naming" mentioned in the Java Policy, though in
principle the Policy only requires classes in the "repository" to apply to
it. I hereby propose this to be added to the Java Policy that *jar's also must
comply with the "hierarchical package naming" scheme...
(Anyone know where it is btw...? the Policy does not state a URL)
