What version descriptors are you collecting?

There are a few reports I could think to run against your dataset, even if
the IntroPoints were replaced with 127.0.0.n (n set to 1, 2, 3, n for each
IntroPoint in respective descriptors list)... or even 1:1 mapped for all
descriptors either a) randomly into a new parallel IPv4/IPv6 space (dot-quad),
or b) serially into a respective 32 or 128 bit number (not dot-quad).

Whether on or off list I could use your collection patches, and a raw
sample of a single recent on disk descriptor from a public service such as
hbjw7wjeoltskhol or kpvz7ki2v5agwt35 so we know your data format.

It's effectively public info anyways, I'll get to it sooner or later, others
already have.
