1. A computing-device implemented method for integrating late bound functions with an external program environment, the method comprising acts of: identifying, using the computing device, a function call to provide to the external program environment; determining, using the computing device, a set of late bound functions capable of processing the function call; and generating, using the computing device, an interface to allow an integration of the late bound function calls within the external program environment for enabling the external program environment to execute the function call; wherein the acts further comprising an act of storing the interface and the set of late bound functions in at least one verifiable file; wherein the act of storing the interface and the set of late bound functions in the at least one verifiable file includes an act of storing the interface and the set of late bound functions in at least one encrypted file; wherein the act of storing the interface and the set of late bound functions in the at least one verifiable file includes an act of storing the interface and the set of late bound functions in at least one verifiable file that identifies a compiler of the interface and a compiler of the set of late bound functions.
