Shared CAD files across a WAN

Users are on AutoCad, specifically Plant3d.  They work in different locations across the country.  Local storage in each location.  Entire project is about 20GB , and drawings about 40mb, but the drawings take properties from the project.  50mb - 100mb DSL IPSEC tunnels in place,  Is there a better way for performance as branch offices cannot work on projects in a centralized location due to the speed?

Thank you!

Do people ever work on the same drawing at the same time? If no, you may be able to replicate files (maybe with DFS Replication) and then use DFS Namespace as a reference so that the users can pull from local server instead of remote server.

Riverbed has historically had great options for this exact use case, especially when using SMB1 with Windows XP. Microsoft significantly improved the network stack to handle file access of WAN connections and the associated latency stating with Windows Vista and Windows 2008, but it could still be worth a shot. I would look at getting a copy of the files locally first though. Branchcache is another option.
