Kaiphus Kain Thanks for your question. I think you are referring to the recent announcement about our Custom Launcher.
To clarify, we are actually working on a separate Windows app, what we're calling the Shards of Britannia Launcher. In the future, all players will use this to load the game instead of loading the game with the Legends of Aria launcher or loading the game directly from the game folder.
We've been given nothing from Citadel Studios except for approval to make our own custom launcher app and use it with the Legends of Aria client.
With the custom launcher, we will be able to potentially add functionality on top of the existing client without having to make changes to the client itself, since we are currently unable to do so.
As per the Login Server, no that is still in full control of Citadel Studios.
Hopefully, this helps clear up some confusion and answers your questions.
