We need a web server utility that recognizes the origin of the visitor (like in ad servers) or scans the browser language of the visitor and then automatically displays the content in relevant language. That would be more productive than offering manual selection of alternative languages for your international website audience. I suspect these things might be available out there but my browsing experience has not thrown up such instances.

Extending the idea further, when web based telephony rules, you could be greeted by your local language by the IVR system when you click-and-call an overseas company. “No one speaks English here. Please hang up.” You could probably do that right now even with telephony 0.0 utilizing the Caller ID header.
