It would be nice if newer browsers could start including average speed data in the http header. Then you could have servers that would offer up more or less weighty versions of the website based on projected load times. For browsers not attaching this header info, you could just assume the worst case scenario. Even if maintaining multiple versions of the site would be a pain, it would at least be nice to do something like this during a site redesign. If a user has a fast enough connection, and load times aren't projected to be terrible, serve up the new heavier site. If not, serve up the older site. Then you could get some metrics about what percentage of your users still need the old design around, and how important it would be to cut weight on a redesign if needed. I'm a technical lightweight so i might have messed up some of the details, but hopefully the idea is still interesting.
