I don't have a clue what you can do with InDesign documents or what Kinko's is, but I am pretty sure that running some software "in the cloud" is not the (only) solution. Other solutions probably would be a different licensing model or an open data format, possibly converting your InDesign document to an open format beforehand, or logging into your computer at home from someone else's machine, or in some other way using software on your machine at home remotely, or probably numerous others, most of them probably with a huge advantage in terms of privacy/resistance to surveillance over a solution where you process your own data in unencrypted form on other people's machines.
