I>clicker is in the process of testing a web application that, apparently, can be combined with the physical i>clicker remote. The app would run on a computer, iPhone, or any other device with a standard web browser.

They are testing it this semester, and there is an e-mail address on the web page for people who want to try it in their classes.
I pass this on based on my reading the web page. I know NOTHING about it.
