If you are on the same sub-net the only way would be to find out who has there NIC in promiscous mode. If its out on the web AFAIK its not possible.
Sniffing is a passive "attack" and is very hard to detect. If you are worred about someone sniffing you passwords the i would recomend implementing some form of encryption to prevent this. That is the best way to stop someone from watching what you send.
