It still wasn’t resolved after 6 months of talking to Riverbed, and is ongoing I believe.

It's been quite a few years since I've played in this space, but I do recall that CAD files were (once) the bane of WAN Acceleration products everywhere.  

Someone explained it to me that when making even small changes to CAD files, the structure/contents/order of the file is changed so drastically that traditional caching/diff methods become ineffective.  I find this highly ironic since the size of these files and the inevitable number of revisions that must be sent around the place must be staggering...

As for the OP - Riverbed licensing is/was based on number of active sessions through the appliances - be VERY optimistic around these numbers when sizing your appliance as exceeding them will leave you with unaccelerated traffic flows and very bizarre performance issues.
