Read .pages files in Windows
Well, it's not exactly a solution, more of a workaround, but Google Docs now read .pages files and will in many instances be able to show the contents. It depends on what version and how complex the .pages documents are.

The current version of Pages will be able to open Pages '09 files if you have a Mac owning friend.

Thirdly, if you rename the file extension to zip, and unzip them, you will see a preview of the contents that can be of some use to you.
