Nic, what makes you think that that DNS indicates an open wireless AP (do ISPs contact their customers and determine whether they are running an open wireless AP and then change their DNS?) as opposed to a fixed wireless broadband connection or a 3G or other cellular data system? In fact, rmci.net is a division of Velocitus, which offers fixed wireless broadband to rural customers, indicating that your spam originated with what amounts to a DSL customer, not a mythological "drive-by spammer."

Jerry, that argument doesn't hold water. Losing an account for a spammer is the most minor of inconveniences. Spammers have *no problem* spamming from home, using desktop PCs that cost a tiny fraction of the cost of laptops; compare that to switching to a laptop, buying a cigarette-lighter charger, getting into your car and driving around aimlessly -- why sould you do this, when you can just use well-understood techniques for locating open SMTP relays or other means of spamming?

Should the risk that someone, somewhere, someday *might* use a new beneficial technology to do something you don't like preclude using that technology at all?

Spam wouldn't exist without bulkmail software, but we don't ban bulkmail software. Other tools that are used in the production and dissemination of spam include perl, Python, Google, TCP/IP *und zo weiter*.

Printing to remote printers over IP networks is old news, and you don't need a wireless AP as a launching point for this sort of "attack" -- at best, you can use up some toner and paper, and doing so hardly threatens the safety of the free world.
