Difference between PBEM and TCP/IP

[dmm]

If MM makes TPC/IP, I hope they'll put in the abilities to:
1) Set a (player-negotiated) time limit / turn (which can be changed upon agreement), and
2) Watch other peoples' battles (CNN on steroids), and
3) Have an integral chat window, with public and private rooms (with option that private rooms are only available to players who've made contact in the game).

These abilities would relieve the boredom factor, increase the social aspect, and improve diplomacy. I might even use TCP/IP under these conditions.
