It is even possible to connect two firewalled peers through uTP's NAT traversal feature.

This allows µTorrent to punch holes through routers and firewalls to increase connectivity and improve speeds. In addition, uTP in this version has added its own form of STUN, a method of getting incoming connections without direct connectivity to the Internet. This does not require any additional setup. This will allow you or other users on the network to download their torrents but still allow others on the network to function with little difference. UTP is an alternative communication method for BitTorrent traffic that allows the client to automatically regulate its bandwidth usage to avoid adversely impacting your internet connection. With BitTorrent, you can download files faster and contribute by sharing files and bandwidth.

It was designed to use as little cpu, memory and space as possible while offering all the functionality expected from advanced clients. ΜTorrent is an efficient and feature rich BitTorrent client for Windows sporting a very small footprint.
