Thanks for the link to the web site! I saw it once before but lost the URL. Glad to see that they are expanding and adding kiosks at other airports! I agree that the INSPASS program is a blessing! I've used it 6 times (LAX and SFO) with 5 successes so far. I've actually avoided coming back through DFW and SEA because they don't have INSPASS. The only thing I wish they'd add is an expiration date on the card, so I can renew it in time.
Also, regarding dgolds post earlier, INSPASS gets you thru immigration quickly, but you will still need to go thru the usual customs lines.
