A mechanism like NAPC or an auto-download from an in-company server would be possible as a module in and of itself, if the core provided a way to hook the module load process. It's already been mentioned that there will be a list of implicit use's you can stick somewhere and they are used for every script. So you could install a suitable module manager, and such things could be created by the community.
Just musing, you could have a CORE::HOOKS::find_module that's called if it has been defined.
