Putty is a great Telnet/Remote access tool, I though I'd give it a mention. While the windows binary may write setting to the windows registry. Socialist Sushi has made a package that runs portable for your pleasure. PortaPuTTY is everything you love about PuTTY with out the registry use. I could plug into Putyy-Portable, but that uses a registry file and isn't much different from running Putty from a batch file calling different system variables(massive lack of stability/capability). Sorry John, I have to go With SS on this one, PortaPutty is the winner for this post.
