An article from the US publication, AIA Focus, entitled Digital Project Collaboration, looks at two US solutions: Newforma (see previous post) and ReproMAX DFX (sic), "a web-based, third-party document management system established by a consortium of more than 225 international printers familiar with the AEC industry".
A user of the ReproMAX DFS (correct spelling) describes the shortcomings of using file transfer protocol (FTP), "witnessing a situation where a developer asked a designer to show him his FTP site and there were 60 files on there and no one when each file was looked at or updated by consultants".
I had a quick look at how international the ReproMAX service is. Its network covers most of the US, plus 15 CallPrint locations in the UK. ReproMAX DFS was developed by Adenium Systems (see my 27 April post about its integration with Meridian Systems Prolog).
