Wiki Browser
A dedicated Browser (or firefox module) to find some terms, words, images, sounds, electronics circuits, etc. for all the web which could download directly from the url the raw wikicode and parse it locally on each Browser. To reduce server processing. With all functionalies that mediawiki have but in a dedicated Browser .
Just doing the script to format the current wikimedia's content as a shortly xml output will be enought, so we can develop a client.
