Network access though a Bluetooth Access Point
Authored by: MichelP on May 05, '03 09:05:33AM

Pushing that a little further, you could imagine networking 2 Macs (each having a Bluetooth interface) together!...
One Mac, acting as a gateway (becomming the access point), publishing its incoming serial port (like the standard Bluetooth-PDA-Sync) and running pppd to serve ppp connection.
The other Mac (client) setup a bit like described in previous hint, with an outgoing port pointing to gateway's serial port.

The beauty of that is that the gateway, could be actually sharing its ethernet/airport Internet/dialup PPP Internet connection, hence acting as a router, delivering Internet service to the client.
...still with Bluetooth bandwidth limitation tough.

More info on pppd&nat setup to share internet connection (just simple applescripts to run on the gateway Mac) on:
(several macosxhints on the topic too, but applescripts are just one click!).
Deriving these for just a peer to peer connection, run this Applescript on the "gateway" Mac:

do shell script "sudo /usr/sbin/pppd /dev/tty.Bluetooth-PDA-Sync 115200 noauth local passive noproxyarp asyncmap 0 silent persist &" with administrator privileges
(all in 1 line)
router will get IP, client (change if you want other addresses)

to stop the gateway, put that into an AppleScript:
do shell script "sudo killall pppd" with administrator privileges
