FWIW...I think it'd be a rather nice addition to a guide rail for breaking down sheet goods.
I only have two issues with it. The first is the initial squaring of the Woodpeckers handle to the guide rail. Using a 1281 is rather hokey.

If you're off by only .005"-.006" at the 1 foot mark, you'll be off by .040"-.050" at the 8 foot mark on a sheet of ply. I'd just use a small Woodpeckers Saddle T-Square and 2 pencil marks spaced 95" apart on a 8 foot piece of plywood.
http://www.woodpeck.com/sdltsqr.htmlThe second issue is how to maintain the perpendicularity while actively using the bulky assembled items. Because we're talking about an 8 foot lever arm (the Festool guide rail) it doesn't take much of a jar/bump to knock this assembly out of square. I think it will work, however, you have to be very, very careful when handling this assembly.
As far as price goes, I think they're in the ballpark. As a matter of fact I was quite surprised to see it under $100.

After watching the video, it appears that they may be using MIC 6 cast tooling plate which runs about $20+ per square foot. Add in machining time, clear anodizing, fasteners, extra bit & pieces, labeling, QA and packaging and the costs add up pretty fast.
