Nothing complex about two images exchanging messages, its not even complex to transmit objects via fuel, you even transmit a debugger or any part of the live environment or even make an "internet" of images that join objects together. Sky is the limit. Pharo already provides you will all the tools/libraries to do this.��

A streamsocket (not to be confused with regular sockets) will delay the messages (a collection of bytes) until they arrive to the receiver or until they have reached the timeout period. Offline mode is pretty much obligatory even for plain old internet web apps because of drops in connection or the plain fact a connection can become slow.

I used streamsockets in my Pharo to Python bridge (Atlas) because the execution was not necessary synchronous , I was sending Python command to a 3d application from Pharo and I had to make sure that the bridge was working even in the case of a command that could take hours to execute like a rendering process.�� ��
