Barbed Versus Barbless
Used a Steelhead once in an AutoCAD application. Corporate IT, diligent but some 3500 miles away on the other side of North America, were constantly scratching their heads and tweaking it to work for intolerably slow DWG saves.
Turns out it couldn't dedup DWG saves because AutoCAD "uses a type of error-checking that causes nearly every byte of the file to be changed during a full-save, even if the data itself was barely changed" as Autodesk puts it. Since a typical AutoCAD install is setup to do frequent saves for obvious reasons that provided an entertaining year of agonizingly slow server access while we were all in the dark. Eventually AutoDesk provided an explanation and a fix.
A Virtual Steelhead wouldn't have solved that problem but it may have saved the cost of hiring local IT contractors to visit the office multiple times to attempt to solve a problem that wasn't the Steelhead's in the first place.
