Need opinions on F1 Challenge multiplayer

For those of you who have used the multiplayer part of F1C, what kind of
problems do you usually have with it? What is the most people you've played
with at one time? Has anyone ever had a LAN party with it?

Sorry to just barge in asking questions, but we're looking at possibly
running a LAN-type party with an F1 Challenge mod and I was curious what
kind of problems we might look for and what the most people we could run on
it at once (a real world opinion and not what EA says)

Thanks for your help guys!
