Idea for a cool AJAX-based project: a web-based slide projector
Thanks to tools like HTML Slidy and S5, you can build nice slide shows using HTML, CSS and some Javascript.
But what if you are lecturing at a distance? Imagine people get to watch you by videoconference while watching your slides. How do they know when to go to the next slide and so on? The solution, I believe, is to use AJAX. With a little PHP or Python based server-side script, you could control which slide must be displayed and anyone looking at your slide show would be automatically moved to the right slide.
That’s it. So simple. Anyone dare try it out? I bet it can be done with 200 lines of PHP and 200 lines of JavaScript, no more.
For extra points, make it so that the administrator can upload a picture (maybe using a webcam) which gets displayed in the right top corner, so that it feels a bit more like a videoconference.

like i said to you in my e-mail
https://www.webhuddle.com/
this will save you at least 400 lines of code
also you can use marratech free version if you have 5 or less concurent user
also the FCS clone in open source software called red5
http://osflash.org/red5
will be the perfect platform for this kind of thing once finished

of course that being said i am not here to stop you to write code
if you want to do this drop me a line maybe we could look at the posibility.

Benoit: marratech free version doesn’t support application sharing so it is only for videoconferencing. I want to project slides.
I tried webhuddle (https://www.webhuddle.com/). It sounds wonderful. It looks absolutely great. But I don’t know how it can parse PowerPoint slides in pure java.

Webbrush is not a web tool, it is an Internet Explorer-only tool. I cannot take seriously web tools designed only for one browser.
