Therefore, could I put in a request for a "greenlist"
feature to allow
sysop approved links to be generated without rel="nofollow"?
There are well over 8 million external links in enwiki alone, including well over a half million distinct domains via HTTP.
A greenlist is not a remotely sane solution because of this...
A Bloom Filter could hold the entire 8 million urls in about 1 megabyte with a false positive probability of 1% or 1.5megabytes with a 0.1% probability.
Whilst loading in and out of PHP wouldn't be nice, a separate service is certainly feasible.
