It's also true that if a sizable group of network operators were to actuall=
y=20
deploy source address validation (thus proving that it really is a reasonab=
le=20
approach and doesn't carry too much operational or vendor implications),=20
then it would be quite reasonable for those operators to bring the results=
=20
to NANOG and get it recognized as a best current operating practice for=20
networks of similar design/purpose.

There is a significant difference between a "best current practice" (BCP)
document from the IETF (a technical standards body) versus one which actual=
ly
reflects the well-considered best practices of a large network operator for=
um. =20
The latter would be of some interest to governments (and groups of governme=
nts)
when they ask for any options that might help with their growing spam and D=
DoS=20
concerns...
