Use of ad-hoc party is apparently much, much easier than xlink-kai though as mentioned above it does require a PS3 unit with a wired ethernet connection. Right now you need a (free) Japanese account to use the service but there are guides all over the internet, for example, here...

Not that this helps you if you don't have a PS3

I am curious though if there is anybody here interested in trying out Pure/Pulse via ad-hoc play. I understand that many of the old-timers have things figured out via xlink kai but for newcomers, ad-hoc party seems like a better choice?
