It would be nice if it was easily visible to see the clients that amule had come in contact with, as well as using numerical identification for the cookie-cutter username clients in your upload list, such as emule with the username "http://emule-project.net" would become "http://emule-project.net User 134" I believe with a small map you could accomplish this fairly efficently, just storing the user-hash, having a default numerical association for the cookie-cutter usernames, and then an unsigned short or something for the numerical identification.
