How to make Google Scholar work for the distance students

OK, I haven't had a chance to try it from off campus, but we're introducing Google Scholar to our EZProxy server in the hopes that if we authenticate our students first, they will be able to access the content we have licensed when using Google Scholar.   Of course this would mean the student would have to come to our library page first to go in to Scholar through our door.

Here's an idea though.  What if libraries were able to work with Google to provide them with some proxy information, and what if Google allowed folks to use their appropriate proxy info right from the Google Scholar page?  Here are some images I slapped together to illustrate what I have in mind:

Right on the front page would be a question along the lines of, "Are you affiliated with a College or University?"

An off campus student or faculty member would then be taken to a page that would look something like this:

The student would either drill down geographically, or (why not go to the strength of the tool) search for and find his/her home institution.  Select it, and from that time forward their proxy information would be correctly appended (or prepended, I guess would be correct with EZProxy...) and any search results would know the student was allowed acccess to Ingenta or whatever, just as if they had been sitting on campus.   I think the student would have to authenticate before searching in order for this to work.

The marketing twist - since Google Scholar knows which institution the student is affiliated with, the full access links should read, "access provided by the University of Calgary Library" or something similar so the students are well aware that this stuff isn't really free.  And of course this would also allow the Library Search bit to work as it does for the on-campus folks.

It might work something like this:

And that's how I think it could work.  Aside from the bit about getting Google to go along with it, what am I missing?
