But ... what does "hosting" mean? Today? These days it probably does not mean providing an environment in which you can deploy your arbitrary (Perl ...) program. Your edge-case scenario is no longer the profit center, and it never again will be. The market is now dominated by customers who realize that they can "deploy their web-sites," more or less, without engaging custom programmers at all. A commercial offering which fundamentally consists of "access to a shell prompt"is no longer commercially viable – therefore, commercial providers no longer offer it. It is now possible to directly catapult into "the final goal ... a deployed web site" mostly without requiring the customer to fully engage with the underlying technology at all. Sorry to disappoint you, but ... "tens of thousands of paying customers who 'just want a web site' really don't give a damn about your language, whatever it is." Sorry. Welcome to the new world.
