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.

NAME
burgerspace-server - UDP server for the networked version of BurgerSpace
SYNOPSIS
burgerspace-server
DESCRIPTION
burgerspace-server is a server that accepts connections from BurgerSpace clients to allow two players to compete with each other. One
player controls the chef and the other controls the egg. Other clients can connect as spectators.
burgerspace-server should be started in a terminal. To terminate it, give the Ctrl-C sequence or use the kill(1) command with the server's
process ID as the argument.
The connections use the UDP protocol. The --port option can be used to specify a non-default listening port (see below).
After the server has started, the user who wants to control the chef must start the client with this command:
burgerspace --server=the.server.hostname.com --chef
Use the appropriate hostname or IP address as the argument for --server. The user who wants to control the egg must give the --enemy
option instead of --chef. The --port option can be added to the burgerspace command-line to specify the server port, if the server was
started with a non-default UDP listening port.
OPTIONS
--help display a help page and exit
--version
display version information and exit
--initial-level=N
start game at level N. Default is 1. N must be at least 1.
--port=PORT
UDP port number on which the server must listen for incoming clients. The default is 49152.
