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.
Regards,
Nischay Nahata
