And even then ...

I don't want to be charged per GET, period.  If I'm going to be charged
per-page, it better be via POST, because I may be using a personal proxy
that does things like invoking GETs on my behalf to keep my cache fresh.

I think #4 is fine as is, but perhaps an additional example to cover
the pay-per-page case would be worthwhile?
