Jeff, in your hypothetical scenario, if UP wanted UP livery in their ESP training simulator, they would have to build the content and supply the textures for that content. Keep in mind that "ESP" doesn't even have a user interface included! It is quite literally a "bare-bones platform" as far as "user content," aside from the few default aircraft models included as examples.

Hi FolksA better outline of the I/ITSEC 2008 presentation is at -Microsoft ESP Showcases the Future of Immersive Simulation ExperiencesHTHATBPaul

I have to agree with most of you here-I think ESP is a interesting core platform for flight simulation.

Oh, I can't wait to make the under-runway tunnels at KSTL and KDFW...It might be...it could be...great

I can't wait to fly through the Chunnel ... Mission Impossible-style!Then ... well, then you'll have yourself a flight simulator!
