[fw-mvc] "PHP 5.3 style classes" for plugins

Is there a good way to set things up so that I can use PHP 5.3 style classes with namespaces for viewhelpers, plugins, validators, and the like? The pluginloader seems pretty bent on using My_Awkward_Prefix_ for everything. I would image that, in expectation of the 5.3, such a thing would be possible without having to make my own pluginloader.

Thanks
