account affiliate cart display friend items links matter offer pay products purchase select selected shopping site sites technically

I have a site that I offer products from my E-Junkie account as well as two of my friend's products from their E-junkie sites... (affiliate links). I am wondering if there is a way to make my Shopping Cart display all the items selected for purchase on my site, no matter if they are from my account or the affiliate links. It would be nice if they could select different items on my site, no matter what account they are from, and pay for them all at one time.

Ah! sorry not technically possible
