I think Michael Buckleys post says it all. But you will need a reverse network cable if the connection is directly from computer to computer Else You can use a hub, switch or a router with a normal network cat5 cable to transfer files from one comp to the other.
Or I'm assuming your brother has a 20gb ipod. You could use that ipod to transfer files instead of your 200mb usb flash.
Now here is something I found using google. I knew the first method. But I found another on google. Here come both .....
First: a regular network cable will not work. You need what's called a "reversing" network cable. The problem is that a regular cable will connect the transmitter of computer A to the transmitter of computer B, and the reciever to the receiver. What you want is the "reverse" - you want the transmitter of one computer connected to the reciever of another. (Hubs, routers and the like know to listen to the transmitter, and send to the receiver - so "normal" cables work just great when you're connecting to those.)
Second: you may need to install an additional network protocol. If all you're doing is connecting two computers, you may need to install either the IPX or NetBEUI protocols. It's more complicated than is neccessary to get into here, but these protocols allow computers to identify themselves, rather than relying on some other device to assign them an address. In this case things that rely on TCP/IP will not work. However, if you use Internet Connection Sharing on one of the computers to share a connection, then TCP/IP, and all the tools that rely on it, will work and no additional procotols will be required.
