Anyone know of plans for a shopping cart to be included in Zend Framework?

This is such a common feature, it sure would be helpful. I know Magento has this built in on top of ZF, but I don't want to use their scheme [or their license].

Zend_Cart anyone?

I think (and hope) that this will never be part of Zend Framework.
The shopping cart can't be abstracted enough to make such general class. I think you should read something about Zend_Db, Zend_Db_Table and Zend_Session.

ZF is also used in magento, free opensource shopping cart, you can start with that
