Antispoofing is 'static' and therefore brittle in nature, people  
change jobs, etc. - so, we shouldn't do antispoofing, either?

Enterprises typically don't do this stuff.  They should, and we work  
to educate them, but it's even more difficult in that space than in  
the SP space.

A question I have is whether or not this class of problems is more of  
a 'need the vendors to come up with better/easier functionality' type  
of problem, a 'need the SPs to do a better job with this' kind of  
problem, or is it more in the realm of a 'TCP/IP in its current  
incarnation(s) lends itself these kinds of issues' type of problem?
