I have an idea that should be revised by lawyers.
So let's store these pages internally, with no public access (no copyvio yet). Then make a button for registered Wikimedians with confirmed e-mail address, protected by a captcha, that will e-mail the stored page. This is not a public redistribution. With pressing the button one must state that he/she will use the source for veryfing a fact or for correcting it, under some kind of fair use. This may perhaps qualify as an internal use within Wikimedia.
A similar example: I can easily check domain.hu for any Hungarian domain if it is free or taken. But if I want to query the detailed record for it, I must press a button and state that I need those data for private purpose, and I am not a machine. That's where my idea comes from.
