I, for one, don't think that the "estate bait" would happen. Those peasants would have to come from somewhere and you would be severely hindering your realm as a whole to set up a trophy estate to attract a new player. Definitely not something that is repeatable, at least.
I don't know the view on inserting some AJAX elements into the screen, but when you select an estate it could bring up the realm map, realm and region description on screen real estate. That is, if we are set on making the choice *just* an estate.
