No suggestions. I cannot think of any 100 percent reliable way to check this. Proxies, from the client perspective, look the same as clients. As you suggest, high port numbers are not an indication of a proxy server. Clients use high port numbers as well.

You might be able to guess proxies from large companies that direct the vast majority of traffic thru proxy servers by a study of the IP addresses of the connections. This would be a good guess for large organizations. You can also tell clients that are more-than-likely not proxied because of the hostname, i.e. the DHCP names of clients with Roadrunner, @Home, etc. This would be intelligent guessing (at best) and incomplete.
