I haven't gotten to that point in the series yet, but WebSockets are on the agenda, probably using Socket.IO.

The only client side library we're using at the moment is JQuery, other than test frameworks.

In general, the show tends to focus on understanding things deeply before applying frameworks and libraries. JQuery (and eventually, Socket.IO) is an exception because of how it abstracts away browser differences.

Oh, and we're using Raphaël to abstract away vector graphics differences. (In particular, IE 8 uses VML and the other browsers we're supporting use SVG.)
