Click "End Turn". Select option to keep game open or to close it. Use preferred method to upload files to PBW site. Scan for game files. When available, download files. Load into SE4. Play turn. Repeat cycle.

Yeah, that sounds a lot better than true TCP/IP where you only click "End Turn" and the game notifies you when the next turn begins.

As to some of your other comments, many people only play multiplayer games with only one other person. If the host gets eliminated, the other player wins. Schedules are not an issue. If one player has ISP problems, postpone or play by modem. The solution to the problem should accomodate this type of play as well as play of larger Groups.
