Not to sound like a jerk because shock and micah and others have put a lot of time into the software, and in some ways it is more flexible, but this is why I went the hardware route for my input. Far more expensive but it works 100% of the time. I am sure these last kinks can be worked out though, and it makes it possible to actually dual box without hardware... but there are some limitations of software that should at least be considered when you put your setup together.
