Do we know yet if the JPN, NA and PAL versions of adhoc party can "communicate" with each other? Or so we all need to stick with one version if we want to race?

Probably I will download the PAL version of adhoc party over the holiday. I have the 50 feet of ethernet cable ready-- but dammit it is a lot of work to string it up in a fashion that is stable and attractive (or at least, not too unattractive!)
