I successfully completed an “offline” build for Android using the latest 3597/Solar2D build. I’m going to start testing the build and consider taking it LIVE if it operates properly on each device.
If you are on Windows, you will not want to do this until @vlads gives the okay; because once you configure to do offline builds, I’m not sure you can get back easily to the online builds. However, if you are on Mac, you can run the offline builds side-by-side with the online builds.
Ultimately, Solar2D will stop using the Corona servers at some point. So, the sooner you can get your apps to run with the “offline” version, the better prepared you will be when that’s the only option; my two cents.
In my case, I’ve had to work with the makers of the plugins I use to support Solar2D offline builds; it was rough for about two weeks, but then it all came together, just as a good-working community for an open-source platform should.
