Encryption is a good idea for any wireless network. I believe bluetooth has a little more in this respect over 802.11 but I do not know any sure statement whether by itself it is enough. Eg you may need to run IPSec or similar over any wireless link to secure your data. > * We already have some bluetooth devices. > * Most of us use notebook computers.

Refer to the "bluetooth" chapter in the handbook: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-bluetooth.html (might be available in other languages too...) Certainly it appears that RFCOMM is supported which should let you do what you want, both serial (eg GPRS) or LAN. I've not done it myself - will have to give it a try one day. Regards, Tony
