AIR Run the same app twice for testing

I am working on a multiplayer application and I need to run for testing the same application twice (so one can create a game and other can join). Is there any feasible solution to achieve this without:

• Creating a .exe out of the project;
• Using two computers

Ideally I should be able to keep one of the instances constantly opened while the 开发者_JS百科other can be easily recompiled for testing.

You can use different application id's. Under Windows, I can change swf file of installed application and run it, it doesn't complains, so you may overwrite app with newer version without reinstall.
