I had a version of Cameria working but it used a (very nasty) xss hack to allow the avatars to appear and to facilitate the chat balloons above each avatar, maybe this idea could be revived using layers and node.js ?

It was pretty weird in the beginning, but after we got used to fooling around with it we actually found some neat use cases (remote collaboration).

Co-browsing for shopping, etc has been long-done, right? I remember wondering about that years and years ago.

A questionable idea on my list was weather widgets where the weather would be depicted by the attire of a character. A core set of code would run it all, but could be branded according to a celebrity, cartoon character, etc. e.g., on your CelebX fan site, CelebX would be in wet-weather gear for storms, shorts and singlet for a heatwave, etc.

I had a basic idea the other day and built it today - just a bookmarklet that will take a page (news article, for example) and load it in Spanish in the left half of the browser, and English on the right, as a way of trying to learn the language: try to read in Spanish, but you have the back-up at hand for when you get stuck.

http://yubnub.org is good for this. e.g. to compare german and english versions of a wikipedia page: "split {url wp topic} {url wpde topic}"

something user-friendlier would be nice, though. better still, something that would try a few tricks for finding (human) translations of whatever page you're looking at -- going through sitemap files, following wikipedia translation links, whatever other schemes there are out there.

There are plenty of other things you could do in the same field. And could charge money for: many people's jobs consist of reading online information in a foreign language, and they would pay for any help they can get.

This was to work across sites, allowing you to click links with abandon without breaking up the group.
