No one ever seen it working (except that demo video) on N900. Check out "Android inside chroot" thread (still alive, preparing update).
But sure, you can try to contact them and ask them about price. Also, you can hope someone will RE it or leak it's sources :P

EDIT: I've contacted Myriad Group with request for more info.
EDIT2: just found this thread. Seems like some guys already tried to contact them. No or automatic responses only. Gonna write a letter (hand-written one ) to their office adress in Swiss, then call them. But honestly, they are not going to speak with such a small (however interesting) project.
Another option is to separate AD from some Jolla / BB device.
