Pretty interesting piece of web collaboration system. What this site does is to allow their users to upload their power point presentations to the site and then "present" them live without the need of software download. So if you are traveling overseas, there is no need to have a copy of the powerpoint (or the powerpoint software), just log on to their site and you can do your presentation there. No worries about corruption. No worries about your customer's computer does not have powerpoint.
