Ad 1. I don't have idea why, in this version I'm using my linux server to test with others.
Ad 2. I guess this is new system pack feature
You have to check this one.
Ad 3. Not exactly, but player will be invisible for others and others for him.
Ad 4. No. This is timer, not render function
If you want less interval use onRender.
Ad 5. This feature should be avaliable in new version.
Ad 6. Well, my bad. Functions are into MP engine, but are not binded.
Ad 7. In dev 8 probably u were using Nubzior module, which is much faster, becase is written in native C. Well I guess, I will have to bind file class in multiplayer for better performance.
