AIN Monitor_For_Change functionality is used to implement an AIN based call retry service and an AIN based enhanced call waiting service. In particular embodiments disclosed herein, a network-analysis application requests and receives version information from a version of a network-management application. The resultant fluorous tagged organic compound can be subjected to subsequent chemical transformations, wherein the fluorous nature of the tagged compound is utilized to increase the ease of separation of the fluorous tagged organic compound from untagged reagents, reactants, catalysts andor products derived therefrom, after each chemical transformation.
