Very nice. Would you be willing to give a talk at the next cloud meeting?

When a user visits a website, an HTTP request -- with the client IP, server IP, and current
timestamp in the query string -- is made to an HTTP server running inside of the node.js process.
This information then makes its way into Accumulo as a key-value pair.

Instructions and additional information can be found on the project page. Feedback is welcome!
