EDIT: i've called Oracle on the phone (Darren) and they stated that any original OTN software (which falls under the standard license) is good for educational and non-production purposes, i.e. as long as the downloader uses it at home for his own sake of testing, education, developing, etc. He said that any private individual who downloads OTN files and plays with them at home for such non-production purposes may do so and may even call himself/herself a developer in righteous full claim in accordance with the license. In other words, overwriting the old Oracle files with new ones and testing it is fine as long as you dont sell that to your friend (e.g. titled as an "updated working QVP11 software product"). hope this helps.
