Doing virtual prefetches (*titter*) should be no problem -- nnvirtual
just has to pass along the calls to the underlying backend.  The
problem is that there's no way to say (currently) on a
article-by-article basis whether an article can be prefetched or not.
That depends on what backend it has been fetched from.  

Well, perhaps not.  nnvirtual will be able to ask the backend whether
it's asynchronous, and if not, it'll just return nil for those asynch
calls it can't honor.  Yup.  Should be no problem to code.
