Linux/Office

Has anyone had any experience with a similar scenario? An small government office with 15 machines all using MS Office. All files in and out are MS Office format. The possiblity exist for replacing the Windows/Office installs with Linux/StarOffice. The key is that all files have to be flawlessly and seamlessly intregrated with other offices which insist on MS format. All of the local office machines are on their own separate network.
