I've been doing the same...trying to understand how the deals are structured and what customers are producing the revenue. I know the last Q stated the % of revenue for their 3 clients but we don't know who the customers are, how the deals are structured ( and how they grow ), etc. Maybe they don't want to let the competition know too much about how they are doing things.
I am hoping for more detail in the 10K which will be coming up next.
