TeamSlide is an ajax-based service that uses a PowerPoint compatible application in combination with VoIP or a landline telephone conference call to provide a simple, yet effective means of presenting over the Web.
It's completely cross-platform and I like the simple user interface. For only $99, I don't see how you can find a better, low-cost solution to running your meeting from your laptop for up to 5 participants (although the TeamSlide site says it's been successfully tested with 20 users).
Try it out and let me know what you think.
