Instant webpage update
OK, got a question.
I have seen several websites where, while you are updating info, it is immediately updating the web page that you are working on. you have not actually hit submit, but there is new content on the page relative to what you are doing, or content from someone else. I think good examples of this are Google with the instant search results and some of the live meeting sites where groups can work together on updating an image/drawing and everyone gets to see it at the same time.
How is that done ? .NET ? Java ? some other language ?
More specifically, what commands are used ?
I have a project where something like that would be really helpful. I'm sitting here in Honolulu deigning something and a client sitting someplace else can instantly see the results without having to hit update and refresh all of the time.

You can do this with AJAX. In the client (browser) you use Javascript to asynchronously send updates to the server. The backend can be written in any of the languages you mentioned - .NET, Java, Ruby, etc.
HTML5 introduces a trivial way to support WYSIWYG editing of pages via the contenteditable attribute. Aloha Editor takes advantage of this new HTML feature.
Closure is a great library for live updates, but its rather involved. Closure is the foundation of the UI for Gmail and Google Docs.

Ajax and a ridiculously fast server side response time.

Well... Wow ! Interesting.
I have been basically doing all of this for years but doing the full page update instead.. All i need to do is rearrange my programming a little bit and actually use the "XMLHttpRequest"
Cool.... i don't have to learn language # 9... HA !
THANKS GUYS !
