Legal Issues for Outside Webcams and Others Privacy?

Jesse Ferrell asks: "My neighbors are asking for me to remove my (weather) web cams from my website because they show part of their houses. Is there any legal precedent to a case like this? I can point the cameras upwards towards the sky more (they are weather cams of course) but it will take time and equipment, possibly modifications to my house. Have you ever heard of a similar situation? What should I do? I'll check the local ordinances and see what I come up with."
