What about some kind of ingame browser wich is providing statistics about yourself and any other driver and lets you join a racing team (or found one). This way, users (team-drivers) can easily see, when the next race in their league starts, (so, race leagues and virtual hall-of-fames should be aslo available) and join with one click. For example, I'm looking for some competition, and join a virtual racing team (like a guild) in WoW or something. now, i can chat with them any time (while racing on any server). A buddy list would also be good. and, of course, hotlapping statistics for any track with any car, automatically unpdated when you're changing the statistics (driving the track in a better time). Of course, lfsword is good, but it's not ingame, so you always need to tab out and cannot chat with someone whle ingame.
It would be some kind of LFS Battle.Net
