Depending on the length of the pipes involved, I've probably finished my shower before the heat can make it's way around that circuit. I can only see it being useful in a location where many showers take place (the next person taking a shower will get the benefit of the waste heat from your shower). In a home like mine (the wife is up at 5:30am, I'm up at 7:00am, the kids bathe in the evening) the benefit would be very very minimal.
You could run the shower water underneath the floor in front of the shower and have a nice warm place for your feet when you get out but I wouldn't want to try and clean the hair out that kind of drain.
