Hi all, I want to connect two applications (1 by image, each one on a different computer) so as as to exchange information (data) between them. So my question is about the best (smalltalk) practices to connect two app/image and exchange data. I imagine either with a direct connection through a network (TCP Socket, Web socket, pure HTTP with Zinc) and/or with a serial connection. At first, without any « security ». But later, information exchanges will be encrypted. Iâve seen some information on how to use SerialPort, or even FileStream. I could do it (or at least simulate it with HTTP). What are the other options ? Socket ? Do we have P2P libs (I couldnât find) with eventually discovery features ? Any comment / suggestion / pointers are greatly welcome. TIA. Cédrick
