There are, in fact, toll roads that try to do that; see, for example, http://www.where.ca/toronto/subcategory_guide.cfm?subcategory_id=25&category_id=24&subtitle_id=142 But it's not foolproof; see http://66.102.7.104/search?q=cache:ELIC5NLh1qQJ:www.canoe.ca/Columnists/blizzard_feb18.html+ottawa+%22licence+plate%22+%22toll+road%22+toronto+problem&hl=en (the original seems to have expired, hence the reference to the Google cache). --Steve Bellovin, http://www.research.att.com/~smb --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
