One of the trade publications I read is called Network World. They have a columnist named Scott Bradner who writes some really interesting articles. Here is one from late 2005.
Recently, there has been a trend of secretly video taping nannies. To make it even easier to check, many people use the features of their video cameras to put them up on the Web. Since many people have high speed Internet these days, this is not very hard to do. The only problem is that most home users don't deal with security, and leave them open for ANYONE to view.
Because the nannies tended to work in places where the homeowners also frequented, unless the homeowners took care to remember the camera was there, potentially embarrassing images could be on the 'Net for the taking.
