I need to create a dynamic shopping cart rule depending on the count of items in the cart.
So I need to listen to an event which changes the item count in the cart (add product, remove product, change quantity).
Does such an event exist or do I have to listen for multiple events?

you can use this observer, it will be triggered whenever the cart is updated.
magento_root/app/etc/modules/Namespace_Module.xml
magento_root/app/code/local/Namespace/Module/etc/config.xml
magento_root/app/code/local/Namespace/Module/Model/UpdateObserver.php
