Slideshare is launching “ZipCasts” which let you make a public presentation on the web using any slide presentation uploaded in slideshare. .Extremely simple: you click on “ZipCast” in Slideshare and you can share presentations in real time. The speaker controls the slides, and can be seen live through his webcam. No download needed. It’s free, but there is a paid version to give you more features and to get rid of ads. Works completely in browser.

Here is a full press coverage of the launch of Zipcast.
