Hi,
According to your description, as far as I know, I would suggest that you may create a shared directory or memory for all the applications on the same
machine, once one of the applications receives the data, make the application upload the data to the shared directory or memory, then the application who requested the data can get the data from the shared directory.
Hope this is helpful for you.
