Do you mean to use VNC to access your data? Because that sounds very difficult to secure and also do maintenance when you are never onsite. The host computer that has your data would have same problems as what this topic is about but now you can't even check for tamper evidence because you are not onsite.

Or do you mean to encrypt your data and upload to the cloud? Then download the data when you need to use it? And how are you managing all the passwords and encryption keys? I think you would need to keep quite a bit of sensitive data on that travel computer so you would need tamper evidence on it as well.

Or I think I must be completely missing out on something here what you are saying. Maybe you can elaborate a bit? It sounds interesting.
