Comment on Lighthouse

Security risk maybe-many would say Javascript is just as much-but this program is quite convenient nonetheless. The genius of Lighthouse is that it configures routers that you don't have administrative access to (Apple routers with NAT-PMP and others with UPnP) or don't want to bother configuring. I keep it running all the time, it never crashes, and uses up 0% CPU. Great price, and really responsive developer. It has Sparkle auto-updating built-in too.
