The problems with this approach:

1) It's not all HTTP traffic, some of it is encrypted, some of it is
non HTTP protocols.
2) Not all HTTP traffic is on port 80.
3) It's not always easy to tell from the Host header what "site" the
traffic belongs to.

Plus I'd still have to manually vet the lists from time to time, plus
write the scripts and a GUI in the first place.

This isn't really about technical know how - I know how all of this is
done, I've done it in the past and I could do it now - I just don't
have the time to do implement and manage this myself.  I want to pay
someone to do it for me.

(Actually, I'd rather not do any shaping of this sort at all, but it's
not my call...).
