Would you need fancy things like regexp patterns and/or wildcards, or
would simple website hostnames do? Website hostnames that I can look up
in a hash will be *considerably* faster. Then the size of the list won't
affect the time it takes to do a lookup. Checking everything like I do
with a ruleset at the moment is very slow, especially if the list grew
large.

Do people want features or speed?
