I am a distributor for both HomeSeer and HAL. They are both great packages. If you are looking at the HAL, you might consider the HAL2000 as well. Which package you choose is really a matter of what you are looking for and your technical abilities. If you're more the programmer type, I would go with the HomeSeer, otherwise, I would go with the HAL2000. Either one is a good choice.
As far as talking to your computer from the shower, sure, you could do it but do you really want to install microphones is your shower? The choice is yours....
