Anytime you are doing a global project, you have additional considerations in document control not at issue on a domestic only project. A global documentation solution that protects your data from outsiders as well as making it available to those with the proper authorization is nigh on impossible without the staffing to support it. I have not seen any easy fixes.
One global company I've worked for used a home-grown system, another used Lotus Notes with QSI's QMS package. Our documentation included (but was not limited to) files created in Pro/E (managed until formal release within Pro/PDM), AutoCAD, Word, Excel, Access, Adobe, email tools. Both companies had FT staffing (and, by staffing I mean more than one person, but these were large multi-national companies with multiple projects to manage) to support the documentation database requirements.
Currently the system I work under is primarily local access. Some documentation is controlled by the originator via write protection & stored on shared drives or the intranet. Other documentation is controlled by CM/DM and can be accessed via the Intranet. Still other documentation is managed manually with hand-written records.
Documentation control only works as well as those creating the documentation. It won't matter how great your system is if you have people who will go around the system for any reason. Uncontrolled documentation is a very frequent write-up by auditors. Make sure whatever system(s) used are documented in procedurally in your QMS if you are subject to audits such as those by ISO registrars.
