Sadly, the solution that was being offered is actually the one that makes sense for the application architecture: Going by the description in the article, there's no central version-control server, just "PCB Designer EE" installs on individual developer machines. The problem is that it's a local workgroup solution, not an "enterprise" scale one. Just because someone calls something "enterprise" doesn't make it so, much in the same way that wishing for a pony doesn't mean you'll get one. Odds are, they would have been better off writing hooks, diff/merge processes, etc. for standard VCS tools and saying that they integrated with those. Of course, I'd like to find out what VC/SCM processses the app developers actually used. (If it's Visual Source Safe, then that's a major fail in believing that you have any enterprise VCS experience.)
