If anyone cares, I found out what the problem was. Chrome updated to a new version of the web socket standard back in version 15 or so. I wasn't aware of the change and so didn't update my version of socket.io which supports the new standard, thus an incompatibility. It should work now.

This just goes to show that you have to be vigilant if you are building sites with the latest and greatest, as they are still under development and likely to change out from under you.
