 Shared library / on-demand loading functionality:
 -----
 I would certainly split this issue into a separate issue.

 What we have done (I'm ready to share the code if wanted) is to implement
 our shared functionality into a series of plugins:

 * A shared "framework" plugin, which registers an autoloader and registers
 a base namespace where most *base* functionality resides (i.e. base and
 utility/shared classes)

 * Functionality-providing plugins, which depend on the framework, each
 providing a certain set of functionalities (usually within classes derived
 from the interfaces contained into the framework, so that one can mix and
 match components)

 * The plugin-dependencies plugin (v1.2 by Scribu + patches) to try and
 avoid an inconsistent mess

 Hence, the "libraries" versioning here is not based on particular class
 versions (which has the potential of becoming messy) but of *library*
 versions (just like it is done with sonames)

 E.g.:  "library" A v1.2 provides versions x, y and z of classes Foo, Bar
 and Baz respectively. So another plugin depending on this shared
 functionality needs only "Depends: library (>= 1.2)"
