In the meantime I have come up with a solution even if NPG folks cannot figure one out. It is very simple. How about Nature Publishing just deposit's all genome papers in Pubmed Central and thus even when the money making machine of Nature switches some setting and makes the papers not freely available at the Nature web site(s) for some time, the papers will still be officially free in Pubmed Central. I think this is probably the only solution I would trust given that this is at least the third time this has happened.
