I would probably suggest leaving your CFCs with all of the cftransactions as they are, to maintain the black box characteristic. Then I would build some sort of log in the webservice that is invoking all of these other cfcs, to track what should be undone if some step fails. Throw it all inside a try/catch block and then when you have an error, throw an exception, and in your catch block, run through the undo steps. This is analogous to what the database will do when you use transactions, but since you want to do it across multiple cfcs you have to manage it yourself.
