1: yeah, i think it would make playing online much easier: just log in to glest.net
, see who is online, ask for games and so on. just like in good old bnet. maybe the masterserver will even support registering one day? however, imo a good online playing system is the best step to get a playing community, aside to the modding community in this forum. and it would be a shame when so many good mods aren´t played by anybody
2: i don´t see a reason why irc should not be used. also, it would be really cool to have the possability to chat in the lobby without the need of running mg the whole time because you could also use a normal irc client. maybe you can turn of some features that are not needed like DCC. i don´t know.
3: didn´t find any that seemed to me to be better.
