a portable/ no install version of design review that could be emailed or run from a usb drive

Description:
users could download the portable version to keep on a usb drive in case they need to look at or mark up a drawing on the go or send to a client that might not have admin privileges on their computer.

Feature Affinity:
When I freelance the simpler I can make it for the clients the better and many of them either don't have admin privileges on their computer or are nervous about downloading something. It would be amazing to be able to simply include a copy of DR with any hot fixes I need already installed along with the dwf's. I know their are DWFx files and Freewheel but neither are as full featured as Design Review
