Writing a small perl script to read a log and print who's IP is who's is
easy, but that won't tell you who accessed via another proxy and it won't
tell you who is who when they are 'IP masq'ed' or using Network Translation
behind there firewall. (Or worse using 'FTP bounce' to access sites...)

All you could hope for the the upstream provider of the visitor.
