It's a good alternative when wireless, and wired, technology is infeasible. When setup correctly it's link stability is greater then 802.11x, but expect speeds in the range of 4 - 10Mbps and about half the range of a typical LOS wireless link. YMMV, oh and the spec does include encryption, 56-bit DES I believe. For the most flexibility look for Ethernet bridge devices. The other one your thinking of is called BPL, Broadband over Power Line: http://www.arrl.org/bpl/ A better solution to BPL is fiber on the poles and wireless for the 'last mile', they already have the easements to set everything up but are just to lazy to do it. --=20 BSD Podcasts @: http://bsdtalk.blogspot.com/ http://freebsdforall.blogspot.com/
