Currently it's only possible to export a VRED camera as .FBX, but that doesn't support shift or roll values which essentially makes the export useless when it comes to camera matching in Max or Maya.
Although VRED is a great piece of software, there are often times when it's unable to do the job that's needed. For example, I would like to render an environment in 3ds max, as it has greater control with materials in Vray and a vehicle in VRED. Unfortunately this isn't possible as I cannot import the camera from VRED to 3DS Max.
