A different kind of network sniffer
by Volker Weber
EtherPEG is a free program for the Macintosh that shows you all the JPEGs (and GIFs) going by on your network.
EtherPEG works by capturing unencrypted TCP packets off your local network, collecting packets into groups based on TCP connection (determined from source IP address, destination IP address, source TCP port and destination TCP port), reassembling those packets into order based on TCP sequence number, and then scanning the resulting data for byte sequences that suggest the presence of JPEG or GIF data.

Seems pretty useless to me actually -
For what practical reason might one want to use EtherPEG - or is it just cute to be able to filter JPEGs out of your network traffic?
