I get the feeling you haven't deployed or operated large networks. You nev=

Joel is right: the thing about the outdoors is there's a lot of it. The co=

SLA's account for force de majure (including sabotage), so I really doubt t=

Nahh, I already have a web cam on my Smarties orb. What else do I really n=
