Re: If you have nothing to hide

I encourage network operators (or IX operators, DNS operators, etc) to let
the government know what you think.  Mr. Clarke's crew is writing the
plan, and taking input from many sources.  If you think RPF (or some other
source address validation) is a solution let them know.  If you think
S-BGP is a solution, let them know.  If you think network operator managed
firewalls on every DSL/Cable modem is a solution, let them know. On the
other hand, if to think some of those things are not a solution (or a
really bad idea), tell them that.

I have my opinion, and I've told the government what I think.  But I'm
certainly not smart enough to get everything right (or even most things
right).  Its not a matter of cutting Mr. Clark some slack, but getting
good information from (many?) network operators.
