Hi Jason, As both the SMW gurus said it can be dangerous but I think there is a way to do it, I have a small implementation where I am already using it. For this to work you need to have the information stored in a second source as well to be able to update the information on page refreshes (I use a separate db table). The way to update this property-value is to use the updateDataBefore hook and update the value by fetching it from the alternate source - of course there is some redundancy here but I guess you already knew that by now.
