Remote Controlled Application-Feature On-Off Facility

This morning an idea just hit me of enabling/disabling features of an application/system remotely.
If we add(already have?) a way where a module(per-say feature) has an attribute of whether it is alive or not, we can control the way a feature is available at runtime for that application/product.
We do layering, we would need to put the feature On_OFF switch withing that layering so that would need a standard of packaging/module-ring an application.
Is this possible and how would that be advantageous?
