It's designed for small scale stuff, but this could be very useful for some things, like if you want to display a small table of data to your reader and want them to be able to explore the data a little.
There's a video presentation showing how it could be used for teaching here: http://bionicteachin...exhibit/Exhibit.html
They also have a wiki -- fun stuff.
We also provide a complementary service called Babel that lets you convert data from various sources, including tab-separated values (copied straight from spreadsheets) and Bibtex files, into formats that Exhibit understands.
Important fine print, emphasis mine:
Exhibit currently only scales to a few hundreds of items, but maybe that's all you need. Furthermore, we are working on optimizing Exhibit and on ways for you to smoothly transit over to server-side solutions as your data sets grow.
