The folks who I have discussed the design with agree that, with the short length created (half an axle length), the camber change thru the suspension travel gets a tad bit much. For instance, if the arm length created were 23 inches and the suspension travel is 5 inches, the camber range would be over 12 degrees.

There is/are folks who have tried to minimize this by making the length of the arm longer ala Ford Twin I Beam axles.....they dont look too good on a fenderless car.

The vendor should be able to supply a reference if they sold any of the product....oops....a "good" reference. Good is the key word in that sentence. Ask around, there should be someone out there who installed one.
