A to Z - Omniscient Point of View

Source

 As defined in About.com, the third person omniscient point of view is:

a method of storytelling in which the narrator knows the thoughts and feelings of all of the characters in the story . . ..

I've considered the use of this POV lately and wondered if it would be difficult to write. Initially, I thought it would be the simpler way because you can be in everyone's heads.  No worrying about being accused of head hopping because, well, you're in everyone's heads. So, of course you're head hopping. It's the nature of omniscient. But would it be confusing to the reader if not done well?

Have you ever written in omniscient or seen it done well? Am I making it harder than it should be?
