Pantour suspension hub in "hardtail" conversions

Just had a thought. :)
I don't intend to build a "hardtail" Cruzbike conversion but I just wondered whether anybody had thought of trying a Pantour suspension hub (front type) in the rear of such a conversion? ;) :)
Would it work? If so, would it help soften the ride that much?
Edit. I notice that Pantour also makes rear suspension hubs that will take a standard derailleur gear cluster. Those might work in the front of a Cruzbike conversion (or the Vendetta?) that used a donor bike without front suspension.

Whenever I think about the suspension hubs, I wonder, what happens to the rim brakes. I notice you can dial in exactly which direction of travel you want, but on a fork, the travel direction really has to be about right angles to the rim where the brake pads sit.

Wouldn't applying the brakes have the effect of "locking out" the suspension movement whilst the pads were against the rim though?
I notice that the issue of braking is covered in several of Pantour's FAQs. (Toward the bottom of the web page).

12 mm total movement in a diagonal path, 5 mm up and whatever back. You need the verticle movement, mostly, 5 mm is pretty little for the trouble you go to get it.

When the bike is coasting we have 5mm upward travel to use. We put the brakes on and the pad slides up the rim those 5 mm. I have to say I am unconvinced as on a road bike the pad is pretty full fit on the rim and adjustment would be troublesome, with risk of scoring the tyre.

Now if we put the brake on the front chainstay, and orientated the suspension slot vertically, the brakes would work and we'd just have to get it set up to ensure tire clearance at the crown. BTW , how do you like your tire/tyre spelt? :)

I cannot disagreed with your points John. What does puzzle me however, is that a lot of bike manufacturers appear to have used the Pantour hubs successfully in their bikes. Go figure! :)
I have no connection with Pantour BTW.
In the UK, we say tyre. The same as you guys in Oz. ;)
