First, is it a direct connection? I'm assuming by the chat system you mean something similar to IM. What OS are you running? If this is all done through a web browser, it you have a very low probability of being able to get their IP. If it's done through a conventional chat window, then you shouldn't have too much trouble.
Until I know more, I can only give you the general idea of what you need to do. You need to initiate some sort of direct connection between your computers (so that you don't get the IP address of the relay server), perhaps via a file transfer if it's not already a direct connection, then run a network sniffer/monitor such as etherape, which will give you all the IP's your computer is connected to. Watch for the one who's activity spikes while you transfer the file or chat.
