While my number looks high, it could go either way. It could be higher which would mean that the damage would be greater or it could be lower which means that it's "not so bad" where YMMV.
Which basically boils down to "no one can possibly know". Also, I doubt that the cost for prefixes will be strictly linear. It's in the nature of depletion that not everyone can get what they need/want. The proposal clearly states that its main focus is to prevent prefix hogging if possible and thus limit the impact of a probably frantic migration period and lower the barrier of entry for new LIRs. And while I sincerely hope that IPv6 migration will happen fast, there will definitely be a time when IPv4 will be a hard requirement for any LIR that wants to compete. As you admit yourself, other than doing nothing you don't know of any alternative. Richard
