Hi ed, no unfortunately it can't very easily go on the properties panel because that information is shown on every mouse click and so it isn't feasible to put anything there that can possibly require a lot of calculation. Trying to put calculation-heavy stuff right there would result in weird freezes and pauses while you were selecting objects...

I do expect to have a kind of extended properties dialog that will be able to have controls on it for generating various kinds of information like this on it. But that won't be ready for the next immediate beta though.
