`C-a, a` sends `C-a` to muxed terminal. Sure is a bit harder to remember, but not much. IMO the biggest mistake tmux made was not using C-a by default. I don't know anybody who doesn't remap it - it's far more convenient keyboard-wise, and it sets you up for using `screen` on servers where tmux isn't installed. So go ahead and remap it.
