> However as some have noted, cost will keep it from being adopted. Let's face it, fastening is the last thing considered in a project and the last thing bought. Even for large projects it's at most a few percent of budget and people are desperate to limit it's cost as much as possible.

This is incredibly true IME. When I was working at Xerox, they were in the process of switching to vastly inferior fasteners just to save a couple bucks per $500K machine.
