That is incorrect. The 6400 has Skype compatibility as well. Unfortunately neither TV will allow the use of a standard webcam. You'll have to spring for the $100 LG accessory cam in order to get Skype to work.
I've heard they are basically the same set other than bezel color. The 6400 is sold at big box stores like Sams Club and Costco. The 6700 is sold at Bestbuy and Sears, etc.
I just bought the 55lm6400 from Sams Club for $1098. Just down the road Best buy was selling the 6700 for $1399 so I went with the 6400 an saved $300. I've only had the TV for a week now but I'm loving it.
Below is a screen cap I just took using the Android App. as you can clearly see the skype app highlighted
