It certainly would work and be extremely beneficial in some circumstances but I'm afraid the almighty $ issue would kill it before it got off the ground. The prices of these systems is outrageous so unless manpower could be cut by over 50%, which I don't see is being feasible, governments are not going to be willing to spend the money. Also, for obvious reasons, the length of time required to attach such a system is quite long and would cause major problems in firefighting applications.
