Isn't it the case that Multiplayer with switching hosts/ connections using 3dgs up to commercial at least, is not going to let you do it without restarting the exec file, but you could do it with a custom/ freely available 3rd party network.dll file?

I would expect anyone wanting to make a mmo of any level of complexity to move reasonably quickly to a different network code, unless they happen to have a pro licence. Tell me if this isn't the case - I'm kinda new here.

have a great day
