Joel, I agree that the server MPI approach is a good one. When you say zero installation I assume that you refer to components, servers, and certificates because at least there must be a secure direct (using shared secret) of a shoppingcart to the server-MPI, and likely also a secure success return so that the merchant knows that they payment part etc. is ok and it is just shipping that remains.

As you have pointed out and as the Visa functional requirements spec also mentions (http://www.international.visa.com/fb/paytech/secure/pdfs/3DS_70003-01_FR_Me rchant_Server_Plug-in_v1.0.pdf section 2.4) there are multiple implementation options for an MPI. It may be a stand-alone software component that each merchant must install, or it may be a server MPI that can be run by an acquirer or PSP. My personal opinion is that the server model provides a lot of benefits to merchants and acquirers. A server MPI product can provide * zero installation requirements * simpler integration * no operational concerns * integrated commerce support * future proofing for different schemes Whilst none of these are really 'technical' advantages, they are certainly important. A server model can also prevent what I would label a merchant-in-the-middle attack where a merchant can obtain the cardholder's password by intercepting all traffic between the cardholder and the ACS. Does anyone else have an opinion on the merits of either model?
