I'm in a completely separate group in a completely separate place who happens to have seen this link before. We haven't done anything worth linking to yet, just have a little bit of knowledge about this area since we've been looking at it as well. What you're saying is close to what we've been looking at trying to turn into code. I think the proxy thing is a non-issue. In fact a proxy in many ways could implement a portion of the server-side smartness and accelerate conforming clients on websites that don't implement this. These are some larger issues though, I think: 1) Making the server smart enough to actually do this. 2) Sending the resources in the right order (It turns out the order things go down the line can be significant and this is something that can vary depending on which web rendering engine your user has.) 3) This requires changes to HTTP, unlike the linked proposal, so one needs a way to do it right and a compact representation of the cache information.
