its possible, but not simple to do.

hook the dp function in the client, whenever it recieves a message saying to get/change dp, check against a saved image of the the previous one (or current one if it hasnt been changed, eg clicking on someones contact card), if it's changed (comparing both images, a temp one of the one the code just used and the saved one) put it in the log otherwise dont.

unless this isnt how the protocol works anymore i cant see why it wouldnt work, but your average programmer can't do this sort of stuff.
