Anything running Windows XP will be able to unzip, but it is possible that you'll find a computer that isn't equipped to unzip. I think anywhere but the most remote of locations in US/Canada/Western Europe (I guess I'm not entirely sure that .zip files are as popular in Europe as they are in the States) will have computers that have a program installed for opening a .zip. You will more likely run into trouble in the less developed countries, and then, those computers might not be able to view the .jpg/.pdf/etc. files that your documents are stored as, anyway.
7-zip and Zip Genius are a couple more free Win-Zip like alternatives for creating and opening password protected .zip files. I use 7-zip on my own computers; you just have to make sure you are creating a .zip file as the program defaults to its own .7z format.
