We are one of those institutions that did this -negotiated for lots of content YEARS ago (before the providers really knew what they or we were in for.....) We have locally loaded records from the ISI databases, INSPEC, BIOSIS, and the Department of Energy (as well as from full-text publishers, but that is another story and system entirely.) Aside from the contracts, I can also attest to the major amount of work it has been. We have 95M bibliographic records, stored in > 75TB of disk, and counting. Its all running on SOLR, with a local interface and the distributed aDORe repository on backend. ~ 2 FTE keep it running in production now. Over the 15 years we've been loading this, we've had to migrate it 3 times, and deal with all the dirty metadata, duplication, and other difficult issues around scale and lack of content provider "interest" in supporting the few of us who do this kind of stuff. We believe we have now achieved a standardized format (MPEG-21 DIDL and MARCXML with some other standards mixed in) and accessible through protocol-based services (OpenURL, REST, OAI-PMH), etc. so that we hope we won't have to mess with the data records again and can move on to other more interesting things. It is nice to have, very fast - very much beats federated search - and allows us (finally) to begin to build neat services (for licensed users only!) Data mining? Of course a goal, but talk about sticky areas of contract negotiation. And in the end, you never have everything someone needs when they want all content about something specific. And yes, local loading is expensive, for a lot of reasons. Ex Libris, Summon, etc. are now getting into the game from this angle. We will so feel their pain, but I hope technology and content provider engagement have improved to make it a bit easier for them! And it definitely adds a level of usability much improved over federated search.

But those that I know of have TONS of money and are using a 3rd party interface that ingests the data for them. I'm not sure what the terms of that contract were or how they get the data, but it can be done.
