+1 totally! (including the scaling according to track length)
How anyone could be against this is really beyond me. It means more possibilities. Each server admin can already decide how many connections he wants to allow - so if your server is not capable of handling 42 slots, then set a lower number. And if you don't want to race with more people online (why would you not, though? :really
, join a server that only allows fewer racers.
Hasn't this been discussed before somewhere? Maybe someone even got a link to a post by scawen commenting on this?
Anyway, I'm sure it will come -- probably somewhere on the road to S3, but who knows.
