multi shipping and payment??

hi developer
how to make different store have their own shipping method and payment option ?
example
store A - create own payment & shipping method
store B - create own payment & shipping method
admin - can view/modify

is it possible do that???
please help

Would require a lot of coding to add store_id to the payment and shipping methods and also for the checkout pages to check for the store_id etc
