Serialize as JSON into a MIME field, pull in using AJAX and Javascript templates is a good solution, however pulling out specific items, or searching for log entries becomes harder. However unless you have many entries pr document, it is not an issue to fetch it all in one go, and hide the extra data until you need it.
In my application, I have need to store all changes (and also deletions) in all or selected fields, and to be able to search and find these when questions (often from a customer) arise. The only "limitless" option is to store each entry as a separate document, and pull them in using AJAX. This keeps the content documents "clean".
