 This idea is still subject to further changes, and we want to fine-tune the details as we discuss it more.

-==Gamemaster==
+==Playerless Persistency and the Gamemaster==
-The other goal of this project is to not only make users, but also multiplayer scenarios capable of handling persistent storage.
+Implementing SP and MP player persistency is just a matter of recording game values somewhere. Implementing MP playerless persistency, however, is trickier, since we need another place to store our data which is not on user data.
-Since currently there are no ways to store MP data on a server, implementing it is tricky and requires some tweaking and working around. Fortunately, the workaround is doable by this persistency system.
+We plan to make a MP bot called a gamemaster. It can create games on demand, and watch their status. So, we want to make the GM able to launch several "headless" wesnoth instances on MP.
-Suppose you want to make a sequence of multiplayer games so that one game stores data that other games can retrieve. You put in those games an extra, virtual player called a "gamemaster" whose sole purpose is to maintain a set of game variables, (he can do that, because he is a player) manage them during gameplay, and after the game is done, participate on another game with the changed values. It is a system with limitations (for example, games happening in parallel can't share variables between them) but it leads to a lot of interesting scenario possibilities.
+Storing the data in simple WML files as we want to do on SP and player MP persistency can lead to some problems. Most of them are related to concurrent operations. If more than one game writes to a same file, it could lead to possible mismatches if it is not handled properly. So one solution would be handling concurrent operations in a ad-hoc way, making special code to deal with it.
