Peer to Peer File Transfer

I'm trying to implement a peer to peer file transfer in my application. Basically, I want users who are logged into the system to be able to send files to one another. I've found pages such as this one, [MSDN], which would allow me to transfer files, but I also need a way to monitor the progress of the file.

Can anyone help? :)

Have a look at the related Send method. That will allow you to track how many bytes of data have been sent. I'm guessing that it will be slower, though, because you must read the stream and send it a chunk at a time.
