Most hobby ESC's would not mind a 3.3V signal. In either case, as you pointed out, you can use an open-drain + pull-up configuration if need be. You can drive DC motors using H-bridge chips and PWM output from the IOIO. Some drivers will expect PWM+direction while others will expect an A and B signals or two enable signals and a single PWM. All are achievable fairly easily playing some games with how the pins are hooked up.
