I think he means player data.
There are multiple parts:
1. market server - they ignored it and on Leandro's server you just use influence to buy IO's
2. player data - what character you had and the AT
3. mission data - separate from the client
4. player client - the server build that lets you spawn and use powers and has the maps.
there is likely more I have missed but those are the ones we need to run the game.
Thanks for your reply and to others who've responsed, but, I'm still a bit confused about one thing: From the point of view of a player, I downloaded a client which handled a bunch of stuff, but, that client connected to a "server" which adjucated whether my stuff really happened in the game world and what effects my doings had, e.g., a Hellion died (poor homie!). So, in my mind there are two major "programs", namely, "the client" and "the server." (I realize each part had their own pile of processes that they they were taking care of: chat, market, etc...).
So, when, e.g., a cleaned up version of i24 gets released, then that includes both the player's client and the server's server (what I would consider to be the real game engine and the Dev's side of the equation). Right?
