In order to webcast, you need a stable internet connection that provides at least 100kbs upload bandwidth (which means dial-up connections will probably not work). If you plan to have more than one or two people in a skype call or plan to use video, you will probably need a bit more than that. You can test your bandwidth at Speedtest.net , AuditMyPC.com ,or speakeasy.net . You can install NetMeter on your computer to measure and collect real time data on your upload and download speeds.
