No, it won’t work that way. The image InstaDMG spits out is an image of a factory-fresh hard drive. It isn’t an installer like the Install DVDs are.
The easiest way to restore the image would be to take an external firewire drive and put two partitions on it. Install a OS on one side and use it as a rescue OS and use the other partition as a storage drive. Dump your image on the Storage parition.
Just boot up a machine you want to image to the rescue OS side, open diskutil and restore the .dmg from the Storage parition on to the local drive of the machine you’ve booted.
DeployStudio also has a way of doing this, but I’ve never tried it.
