I agree that home yoga is not the end to all stress problems - you do need to address the issues that are causing you stress!
But, having said that, after I started looking into home yoga practice, visited a few of the best home yoga websites, and tried out a few of the poses they suggest for home yoga pracitioners, I do feel the benefits!
So, if anyone is wondering, I would suggest looking for a few sites that offer home yoga books, home yoga DVD's or home yoga videos, or even free home yoga advice, and giving it a try - you've got nothing to lose!
