Good Faith Estimate

Good Faith Estimate (GFE)
Under the new RESPA Rule, the lender is now reponsible for the GFE.  The problem is, the Lender does not control all the costs of a transaction.  Does that mean that the Lender will now have to control those vendors?  If the Lendor does not control vendors,  how will the title company actually be held responsible for the GFE?
