I support the proposal _and_ Nishal's remarks.

> the policy, as is worded, is potentially ambiguous.  hostmasters _may_ be tempted to say that, as per policy, they have satisfied the requirement to allocate one, and only one prefix for anycast purposes, to an organisation, when, a forward thinking organisation might wish to have more than one anycast cloud.  while having one prefix, is obviously better than zero, it would be _wrong_ to limit this to just one anycast cloud.

> (i guess, the other way of looking at this, is that there is no requirement to _change_ policy if, there is acknowledgement from the hostmaster team that they understand this - perhaps we can get them to comment here.  the task of determining valid usage will still be up to the hostmasters of course)
