You should look into programs such as MyPC or the like. They allow you to access your computer from any computer or supported device via the internet. I know MyPC costs per month to offer this service, but it worth it if you need a constant anywhere, anytime access to your files/programs on your computer. There are other programs out there that will do this other than MyPC, and I am sure there are free ones out there as well. I've only ever worked with MyPC personally and foound it pretty painless and easy to setup and use. You just have to research and see which is best suited for your particular needs.
