MarketPress and PP Virtual Terminal

Client wants to add ecommerce to his site. His credit card solution is Paypal's Virtual Terminal. From what I've gathered though that doesn't really provide the functionality needed for any ecommerce plugin...true from the forum's experience? I was able to use my own business account with Paypal Standard and get an API, set up an example with no problems, but on his PP he has selected Virtual Terminal as his payment solution and that's all manual.

Any experience or insight anyone has would be appreciated. I'm new to trying to use Paypal as opposed to solutions like authorize.net. Thanks!
