Of course, if authentication happens to be achieved, then I guess have the app delete those emails it got through.
Which leads to the possibility of perhaps attempting both strategies simultaneously, but on different frequency bands.

Thus spake Tyler Durden ([EMAIL PROTECTED]) [25/03/05 10:30]: : Has anyone heard of a utility that can search for a WiFi hotspot while : driving and then launch an email?
It's a harder problem than you'd expect - Wifi doesn't have a long range, so you have to detect the hotspot, decide if you can handle or evade its authentication, do that, and then send your message before you've driven out of range.
If you're in range for 100 meters at a 18kph city crawl (or bike) that's about 5 meters/sec so you've got 20 seconds, and it can work. If you're driving 90kph and catch 10 meters of the edge of a range, you've got 0.4 seconds to do the job, which is pretty dodgy - lots of mail servers take a few seconds to really sync up, especially if you've got to do a DNS lookup or two.
Directional Antennas are unlikely to be useful - if you've got them aimed right, you might win, but you're much more likely to miss entirely or have only a few meters that you're in range.
