It is my experience that every vendor does it... When alvarion was breezecom, they did not do it. Now they all do.
Moto did it, and we called them on it. They stopped. Their track record is much superior to Ubi's track record.
But then their SMs were $225 or so a pop... -- Once we IPv6 enable every device on the Internet we will have toasters, baby monitors, and security cameras joining the bot nets which today are populated only by idiots that can not refrain from clicking, "Yes I would like to see those titties..."
