Catalog use data - A collective effort?

In all of the discussion around the next generation catalog and what library users really want, I've had a hunger for some real catalog use data. My first instinct was to think: "Someone needs to get a big grant to gather up statistics and analyze them." Then I remembered: we're in the "let's all get together and do it ourselves" era. I also realized that I do not want or need the perfect, scientifically sound study of catalog use; I want some data, reasonably reliable, but also growing and being updated over time. I want something to think about, not something that pretends to give me all of the answers. So...

Can we (the collective we, not the royal we) create a simple way that some libraries can contribute their catalog use data to a common storehouse? In particular, can we create a way that libraries can create a profile and upload data easily?

Here's the kind of data I have in mind:

• What search types are available? Which of these search types is a default? How often is each search type used?
  
• If there is an advanced search page, how often is it used?
• If there are sort options, what is the default and how often are all of them used?
• What is the default display, and how often is each display option used?
• How many records are displayed on average?
  
• If there are facets, how often is each facet type selected?
• What system are you using? (Vendor, brand)
• What type of library is it? (public, academic, special)
  

In terms of making it easy, there could be pre-defined sets for known systems that tend to look a lot alike, like III. There can also be a list of search types, perhaps the ones defined for Z39.50.

And not everyone would have to participate, just those who are interested in the future of the catalog. No coercion, no requirements. I'd be happy to see the data from a couple of dozen catalogs. Could we do it? (I volunteer to write specs and documentation, which are in my skill set.)
