Deploying IPv6 globally

Many North American based organizations operate with their ARIN issued BGP AS distributed globally. When I discussed obtaining IPv6 space from ARIN a few years ago, they told me to submit an individual request for each of my sites (and they'd issue a /48 or larger based on the site). This is the process I've been following, until now, for my North American sites... My question is, has anyone started deploying ARIN IP space to their global offices? If so, how are you registering those sites with ARIN? Or did they tell you something else? Thanks -C
