That’s correct! I do have spark-server on my radar as a priority for when I return from vacation (September).
The server is definitely a priority, but so is everything else! It’s a matter of prioritization, and this kind of feedback is exactly the thing that helps us better prioritize. When I dig into bringing the server up on compatibility for the Photon, I will definitely be looking for input (and contributions) on what matters the most to folks.
With that said I would also like to make sure it’s clear that the Particle Cloud is ready for production as well. If you have concerns about access restriction, we can help! As a matter of fact, the illustrious @jeiden recently made this lovely addition to our documentation: https://docs.particle.io/guide/how-to-build-a-product/authentication/
I say this to say that if you have any specific concerns about authentication and security on the Cloud, let’s chat about it!
I would also love to get a run-down of the biggest blockers for folks building products with the intention of maintaining their own servers/cloud.
