I doubt it. I have plans for an "application installer" that will pre-compute dependencies and reliably set up per-application lib directories. Different applications could have different versions of a module, but a single application will only have one version available to it. This is not something that the CPAN clients are really designed to do (though they can be made to do the right things with INSTALLBASE and so on). A better specification and design for application dependencies and installation will avoid the need to create N custom CPAN views as a hack to make CPAN clients try to be application deployment tools. -- David
