Been happening for a while - even CC has espoused his "you-beaut" installer. Haven't seen one I like yet. We don't allow user creation of target libraries, but they can certainly create (testing) loadlibs. How useful they are would be debatable - unauth, no access to prod data, but who knows. The data access/traffic issue has also been around for a while. DDF has been a real problem occasionally. For example, "mickey mouse"-ware allows creation of SQL query that hits the DB2 subsystem(s). Something like - "I wonder how much I got paid this week"; so download the entire payroll system to a server, and run the (single record) query there. Then check last pay, so do it all again. Or run the query under a user that is (mainframe) password expired or revoked. No smarts at the user end, so it continues to generate the request (and associated enclave) forever, looking for an answer. Bad design is bad design - goes back to (at least) FOCUS and QMF. Give the end user a poorly designed application, and they'll eat your system.
