Since I am primarily a *nix kinda guy. I can pretty much work remotely as long as I have three things; a computer, internet connectivity and an ssh/telnet client. Often times I find myself on the road and I am unable to connect to any of my servers via ssh or to a telnet server until I reach a place where I have all three of those items. I found a company which offers an SSH/telent client for handheld devices. They also offer other software including an ssh server for Windows, a feature rich telnet server and a full SSH client suite.
