..fishy. One thing I see on my ascii boxes, is ifup, dhcp etc
networking during boot-up, _before_ I can log in. It's down
as I get to log in.
..I can see merit on such network activity on ssh, mail etc headless
server boxes, but _not_ on a "single seat" laptop, unless it's stolen.
..that kinda laptops should and/or should not "call home" home before
its owner has decided when, where (home, work, diner, strip club...)
and by whom (owner, spouse, kids, boss, guest, one night stander etc)
said laptop is being utilized for which purpose (e.g. email, porn, "Hi
mom, sorry I missed church, I'm in love, can we come for dinner?", tax
report, weather chk, espionage etc).
..e.g. the presence and absence of certain bluetooth and wifi signals
can be probed on boot-up to help decide whether or not said laptop
should call home, but IMNTHO only after the owner has set up his/her
own usage policy, e.g. using a laptop usage policy wizard script.

Scenarios always come in sets of three:
best case, worst case, and just in case.
