Run multiple instances of any program

I'm looking to have a program made that will allow me to open more than one copy of an application that usually restricts you to running one copy of an application. For example, Valve's half-life 2 ([login to view URL]) will only run one copy. If you try to open another it informs you that you already have a copy open. I'd like to have a program made to get around that. I know there's invariably problems that can come up when you run multiple instances of a program designed to only run a single instance, but I'll take care of those as they came up. For now I juist need a program to take care of getting more than one instance open. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
