Zipt 2.0, page-304

It's an important point of difference. SDA revenue from wholesale internet doesn't move. But their earnings increases through the deal.

It certainly would be an important point of difference but I'm not sure I agree with this. I believe based on customers they currently have in the VOIP offering, their earnings will drop as they now have to give 50% of their revenue to ZIP. So unless ZIPs solution reduces SDA's COGS cost by more than 50% then their bet result is less cash. Only way this could improve on CURRENT clients is if they start charging significantly more to their customers. As far as I am aware ZIPs IP is a reduction in total bandwidth required to make calls. So the savings is in data usage. Would the savings equate to more than the 50% they are now giving to ZIP?

Obviously there are benefits for SDA in dealing with ZIP, it's just not as clear cut to me as it might be to others. I think many investors may be wondering the same thing.
