controlling IP "type of service"

Thinking about network pricing policies and accepting for the moment
that relays don't grow on trees, I see on p.12 of RFC791 a description
of a "Type of Service" field in an IP packet header that requests
different levels of delay, throughput, and reliability, as well as
specifying priorities ranging from "routine" through "flash override"
and beyond.
        Do any of the popular implementations actually try to set this
field, and does it affect the delivered performance of the network?
(My Unix man page for ip(4P) says "other options are ignored".)
