LiveScript was simply the initial name for _javascript_, if I recall
correctly. As a marketing ploy, Netscape changed the name shortly after Sun
announced Java.
> 2) Can't you do Push with CGI?
Yes, if the browser makes a request and receives a response with a MIME type
of "multipart/x-mixed-replace". This basically allows the server to continue
its response indefinitely. I don't even know if modern browsers support
this, though.
> 3) Doesn't a web server, in fact, listen for unsolicited requests?
Yes, that's pretty much what a web server is all about.

Yes, but the browser isn't going to do that for you. You'd basically have to
install a server on each user's machine. I suspect most network
administrators would have some issues with that.
