Most likely when they do come out, new trees will come out and probably be able to have tin/copper by itself which would help smithing at lower levels. Then again Capentry could be mixed with smithing since u have metal for the stands, door knobs, etc. Honestly i think people should be able to enter your house and the person that owns that house could have items for sale in it or could buy off the house. A whole new way of merchanting :D
