I keep my office desktop running all the time when I am away. I travel mainly with an iPad. I have the LogMeIn Ignition app running on the iPad which effectively gives me a a secure VPN to the office desktop. I then run everything that I want to run securely from the office desktop over the VPN link off the iPad.

LogMeIn does a free version which you can access over the internet direct from a webpage on your laptop. Install it and give it a try before you depart, see that you can do everything that you want before you depart somewhere far away for the first time. Finding out what works from the comfort of home is a good comfort blanket!

Browsing FT etc and other non-sensitive matters I do direct from the internet wherever I am.
