[Wine] How to run mulitple instances of app, each for unique IP?

[maxxjr]

I have a windows application that can listens on an IP address for batch data to process.   The application works under WINE.  The application does not take advantage of multiple cores of the CPU.  I want to configure the Linux PC to listen on four IP addresses (which I know how to do), and then run an instance of the wine app for each IP address.   In this way, I can take full advantage of a quad-core CPU.  

Does anyone have suggestions/pointers on how to proceed?

Thanks!
