You might want to try one first before making those statements. I run an ISP that makes SlipStream available for our users who want it. We find that it does make improvements. However, the amount of improvement is dependent on the settings you configure. JPGs etc can be easily compressed. You re-encode the JPG image using a lower quality setting. You can achieve significant download time savings that way. SlipStream lets to select the image quality setting to give the quality/improvement you want for initial image viewing. You can always reload the original image quality then if you need it. SlipStream also uses a newer compression algorithm than those currently used by PPP. Its not clear just how much more effective this is as its quite difficult to measure. SlipStream is not for everyone. There are other issues where its not totally transparent and it causes issues with some internet services. However, when used properly you can achive significant improvements in download times.
