I've created several webservers specifically for this purpose -- feeding multimedia presnetations in streaming or downloadable format over the internet. Your agreement with your host for your site will determine the limitations of bandwidth and storage, but ekeller is correct. RealPlayer, Windows Media Player, and (soon, from what I hear) Winamp/Shout are three excellent methods for very, very small file size. Quality level is about the same for all of them, with the sole exception being Quicktime streaming format -- but it does require larger files. My recommendation, if this is a hosted site and not one you serve yourself, is to allow your uploaders to do so with restricitions on file size, and select one of the formats and stick to it. Truthfully, it doesn't wmatter which one you use -- everybody has a favorite, but they all work pretty much the same. Once you've settled on the file size and such, then get the appropriate server uploaded and setup on your host's system (benefit to winmedia is that you don't need a server, though rp8 now has similar feature) and go. good luck
