Koen,

The 2 types of connectors I talked about are for two different types of use
level, audience and market. Average  users do not transfer millions of
dollars of payments in high frequencies. The vast majority of them send
small amount of money to their relatives overseas once in a while.
Companies, however, do send millions of dollars in global transactions
regularly for all sorts of business reasons. Recognizing the reality of
these two different use levels and types, I thought it would be appropriate
to classify connectors in similar fashion.

Additionally, please note that I did not say the consumer centric connector
will be of lower quality than the enterprise-grade connector. Every time
one deals with people and companies money, extensive due diligence must be
excersized and appropriate insurance ( depending on the value transferred)
should be considered.

You are correct in comparing the connectors to the different shipping
channels of merchandise in existence today. I'm sure you can see
that bulk shipping of goods overseas by companies  is structured a little
different than a consumer sending small packets of stuff through UPS or DHL
service.
