I haven't done any Off-Site programming with CCP. If I envision this being a necessity, I would sell Total Control (CCGen2 would work for non-direct dealers, although I think even non-direct dealers have access to TC in Canada). This has off-site programming built in as an option. Could be a easy way to upsell since you can explain that you would have to charge door to door to program any changes. Rather than pay for travel, pay up front for the upgraded system and you can reprogram without rolling a truck.
