Oh, I see.  I just took "cheap...fast...and secure" to mean you were 
responding to all three.  Silly me :-)

Sure they will, but not more so than your wifi router which is _supposed_ to 
be radiating the signal.  So the Devolo still shouldn't be less secure.

LOL.  I recall reading something about theatres actually wanting to do that 
in the US, but being scared that some people would claim they had an - if 
not God-given - at least constitutionally guaranteed right to use their 
cell-phone anywhere they want.

Hardly.  You really wouldn't do well in a 1000W microwave.  "If" the general 
microwave background is going to kill us all, it's going to do it very 
slowly.

Ah - I see your point now.  It is, in essence, what I'm doing by using the 
stubby for inside-the-house and a directional antenna point-to-point.

Not to mention more tumors :-)
