Whew! Alain's been doing some marvellous add-ons for the Orbiter Space Flight Simulator, notable the AMSO Apollo mission simulator, and he's been known to be somewhat protective of his work, which is understandable, but until I read this thread, I never fully realized the tremendious amount of work involved in the develpment of flight simulation software.
I admit that I was mildly amused by the ongoing furball between two experienced software programmers, each defending his own area of expertese, but I also respected the knowledgable and intelligent reparte as a means to an end, namely the solving of a difficult technical problem.
I was about to suggest to both parties that they collaberate on linking FSUIPC to Orbiter for Multiplayer and external applications, but it seems that opportunity has passed quickly. Anyway, just my 2 pence worth.
