Standing up a reverse proxy that proxies to (and therefore
impersonates, as far as URLs go) any and all resources doesn't seem
very practical to me -- the above sounds like you'd want a forward
proxy instead (think SOCKS or HTTP CONNECT or PAC)?

I.e., you're proxying clients here, not servers, AFAICT.
