Okay, that is perfectly understood. Thank you! This implies that if we want to connect our company's branches (small offices across the city) with IPv6, we should request normal tunnels from SixXS instead, use AICCU as usual, and request the appropriate subnets later (if necessary and when ISK is high enough). Those are still different physical networks, but they are administered and legally run by the same company/legal person. So in this case, this is not equal to giving away connectivity to foreign persons or friends, we would not violate the terms of use, right? "Can I share my account?" is clear for most cases, but I think in that special case we need more clarification. Anyway, before we proceed further, we prefer to ask you first.
