...you don't recognise half the things these young chaps are talking about:
There are several innovations within the HTML 5 specification that will forever change the direction of the web, and one in particular - WebSocket - that will revolutionize the way we develop and deploy web applications. Until now, bi-directional browser communication has been an elusive goal of the Comet community, usually achieved with an assortment of hacks. However, with recent updates to the HTML 5 specification, developers can now use a full-duplex communications channel that operates over a single socket.
The HTML 5 WebSocket enables communication from the browser to any TCP-based back-end service (for example, JMS, JMX, IMAP, Jabber, and so on).
WebSocket? Comet? JMS? JMX? Eeek.
