We have already built products that download both the applications and merchant information for Verifone terminals over the phone lines. We have two versions of this product: one cheap version for downloading Tranz terminals only and a more expensive one that is able to download the Omni terminals. The cheaper version is $500. I bid the more expensive one as you are more likely to be dealing with the Omni terminals. Some Ingenico terminals use the same protocol as the Omni terminals.
The problem you have here is that in order to develop such tools, the protocols have to be reverse engineered. That is an expensive proposition. We already did that for the Verifone Tranz and Omni terminals dial up downloads. Thus, we can offer the products. We have not done that work for the IP downloads as it would require access to a Verifone VeriCentre system and sniffing the network during a download.
