Getting information from the terminal server client?

Hey!

I'm developing a Windows application that runs on a terminal server and users connect to it via remote desktop. Standard stuff. However, I would like to know something about the user and I was wondering if there's a way to get some information about the client that the user connects from (his local machine). I don't need any sensitive stuff, but something like an IP address or a machine name would help a lot.

Anyone have any tips or pointers for me? Thanks!

Nothing?

Bumping this, but I'm expecting that this won't be something that can be easily performed.
