Well, where i come from internet is very expensive and very few people can actually afford it. Dial up is affordable. By means of implementing a proxy, which compresses all the data and have a app on a computer that decompresses that data and feed that into the browser, can the dial up connection be as good as low speed broadband ?
Picture below for clarity
web<-fast connection->| proxy server |<--compressed data(dial up)-->app
No. Most data is already compressed so compressing it again won't improve anything.<p>One way that it could work would be having the server (really) near the client and pre-cache most links from the visited page.
