Linlin, 

I do not see a technical issue with the EPP protocol passing large packets.  There is no specific performance numbers to dispel the concern, but I believe any packet size limitations would be based on server policy and the performance testing done by the server.  Since EPP rides on top of TCP and includes packet framing based on a network header, there really is no technical limitation that I am aware of.

Do you have any feedback on the interface elements?

Thanks,

Jim

>> I really don’t understand the concern related to passing large image files via EPP.  There is no technical reason why EPP cannot include elements that happen to contain a large amount of data to satisfy a specific provisioning use case.   In this case the client is attempting to create a signed code based on the verification of the input, which can include information like scanned images.
