Interactive Instalation networking -Help

Hi all,

I want to create a interactive installation but a need a way to communicate between a Stand alone app (.exe) and a simple mobile app.

The idea is like this: I want to throw an object form the user`s phone( Mobile App) (picture2) to the Stand alone (.exe) app(picture1)

I do not know how to create the communications with a transform( for position) so the position the cube exits in the mobile app to be the same as one it enters. Or just a bool when it exits than will spawn in the stand alone app.

I have done all the codding in mobile and Standalone, now I need them to communicate by network... but i do not know how?

Please help for good idea!! alt text
