The only thing I use that is harsher than dishsoap is the degreaser I use on my drivetrain. I'll probably use it less often, though. I was thinking about the shower method, and I may use that for more in depth washings, but I think the frequent, little cleaning done right after a ride is the best way to go. It's just been driving me nuts this winter (being my first with a bike), that I haven't been able to have as convenient environment to clean my bike of as I did in the other three months.
