Short answer is: maybe. Browsers are starting to come out with things like this, usually combined with a proxy/pseudo-VPN feature. Opera is one of these, and I've seen some people use something similar for Chrome in web logs. Just a guess, but what these things typically do is pre-load the parts of a web page you're trying to view and do a bunch of optimization things: set browser cache expirations, minimize css and js code, ensure images are compressed, etc. In theory it would save a little bit of data, however, it also adds an extra layer of processing on top of what Hughes' web acceleration schemes are doing. How that works together might have varying results. Not sure the end result would give you any noticeable speed increase or data savings. On top of that you'd be adding another player in the loop that's monitoring your browsing habits... so there's a security aspect as well. Disclaimer: I really hate those things from a web admin perspective, because I see a ton of anonymous malicious bots running behind Amazon AWS, OVH France, and a bunch of random Opera and Chrome VPN "users" in Nigeria (et. al.). All of these use such proxies for nefarious purposes and I seriously dislike giving random X-Forwarded IPs the "403" treatment when they're dynamically assigned.
