Magento Multiple shipping addresses - payment modules

Magento 1.4.1.1 has 2 shopping carts, "one page checkout" and "ship to multiple addresses checkout". We desperately need either: * a SAGEPAY and PAYPAL STANDARD module to work in the multiple addresses checkout, or; <!-- --> * The ability to record an address per product in the onepage checkout, and calculate postage per address. ## Deliverables needs to be done ASAP.
