I'm working as one of the development planners for a popular web proxy. I would like 1 hr interviews with several developers. Currently, the proxy is a curl based PHP script (glype, to be specific). If you have any solid ideas for proxying a browsing experience (like a VPN'ed browser inside of a browser), PLEASE apply to this project. I'm only looking for people with solid experience and am wiling to pay for your ideas.
Current browser-based proxies have significant drawbacks with technologies like flash content. I'm looking for solutions that would funnel all traffic on ALL ports (including SMTP, etc.) from within a browser window through another server.
