Im not sure anyone look in the beta forum, so im will annonce it here as well. There is a 64bit working xCode project in the Beta forum, which you can chechout it here, That version does not contains Gernot source code, but have compiled directly to a files to been used in both armv7 and arm64 code.
That mean im will not checkout its still works in iOS4 and down, so iOS5 in the future would been a requirement (which today is not a problem).
here is the link:

Im will lock this thread, because any feedback should been in the Beta thread instead.
