That's not precisely correct. I think what you meant is that if Exhibit 
could deal in a piecemeal fashion with large data sets sitting on 
servers (rather than downloading whole data sets onto the browser), then 
the scalability problem will be solved. That requires considerable 
server-side logic, which is present in our Longwell project.

Yes, it does deal with remote files, but not in the same sense that 
you're thinking about:

    Data in a Google spreadsheet:
    http://people.csail.mit.edu/dfhuynh/movies.html

    Data in a file from another domain:
    http://people.csail.mit.edu/dfhuynh/projects/data-theft/data-theft.html

    Data in a wiki page from another domain:
    
http://people.csail.mit.edu/dfhuynh/projects/data-theft/bibtex-from-wiki.html

(These deal with small remote data sets, not large data sets.)

We have some ideas how to solve the scalability issue, and we are 
interested in solving it, too. But it is not trivial work.
