This has been an issue since the early days of OAI-PMH, and many large
providers provide such intermediate pages (arxiv.org, for instance). The
other issue driving providers towards intermediate pages is that it allows
them to continue to derive statistics from usage of their materials, which
direct access URIs and multiple web caches don't. For providers dependent
on external funding, this is a biggie.
