RE: How much do you disclose to customers?

["Teicher, Mark (Mark)" <teicher () avaya com>]

Depending on the wording of the contract between the consulting house
and the customer.  Some customers require that one discloses what
network one will be scanning from or potential modem assessment from.
In recent months, I have used a large coffee shop as a launching point
for most network based assessments and then relay via Wireless NAT, but
this is a mere possibility with all the HotSpots and Internet cafes..
