If you *really* want to use ToS to distinguish between "commercial"
and "noncommercial" traffic, you're really going to have to be able to
get *routers*, probably on the boundary between the mid-levels and
campus nets, to fill in the "appropriate" ToS bit in the IP header
while the packets are passing through.
It's really not possible to "fix" everyone's IP implementation at a
site to always set the bit on "appropriate" traffic, but it might be
possible to patch the router between a mid-level and a "pure"
commercial or academic net to set the appropriate ToS bits in traffic
received from specific nets or over certain interfaces.
