You'll have to be able to load (but not attach, of course!) multiple
versions of the same package at the same time. The search paths are set up
so that A imports v1.0 of C, B imports v1.1. This is possible to support
with R's namespaces and imports mechanisms, I believe.
It requires quite some work, though, so I am obviously not saying to switch
to it tomorrow. Having a CRAN-devel seems simpler.
