One way medieval kingdoms raised money was simply to lay seige to another castle & accept money to go away. While in MTW one could bribe the army to join one's faction, it would be a welcome addition if one could pay the besieging army to quit the siege for a lower price than to switch sides. The AI could also try to pay off the player when it was under siege.
This would be a more attractive tactic if a future expansion introduces attrition to the besieging army. Since the player can't be sure he will outlast the AI in the castle, he could take the sure money.
