There is one network related feature I would like:
[*]The .2h file should contain a flag indicating whether it is finalized or not. If this flag isnt set, no Quickhost shall happen. The .2h is used regardless of this flag when forced hosting occurs. "End turn" sets the 'finalized'-flag, while "save and exit"-clears it. No changes otherwise.
Or Dom2/3 should ask whether to upload a turn to a quickhosting server or not: I do not do my turns at once, and reconnecting just to see how much time I got left resulted in quite a few half-done turns...

[*] The server should also ask all connected clients to upload their turn when forced hosting occurs (to fasciliate Blitz-games). Last time I checked this wasnt so...
