I'm guessing the answer is "no" to the relative impossibility of the task, but - has anyone done a study on the ratio of RFC1918 space:ipv4 public space in use out there in the wild today..?
10.x forever yo. It's easier to type.

Now that I have your attention!
If you're in recent receipt of ipv4 space from the new /8 blocks then you'll also be feeling my pain.
If you're a lazy firewall maintainer or a complete idiot in charge of some important packet routing hardware:
1. you need to stop filtering these new address blocks immediately, they have (or will have) some busy internet users on them,
2. you need to review your firewall or wrapper settings on your authoritative DNS servers, you need to answer non-recursing DNS queries from these new addresses,
3. you need to read RFC1918, maybe even cover your small cubicle with its contents, so you know what you should filter.
