What did your acquaintance get for their part? I had a kindof similar situation long ago, where a friend worked for a high-frequency trading company and I had been developing a low-overhead high-precision resource and system monitoring framework. I would supply him development builds of the agents and a web login to monitor and tune their trading systems while I got some free production testing in return, it seemed fair at the time. As things matured and I started exploring paths for monetization, when I approached that trading company about a possible contract my "friend" demanded half ownership stake in the business in return for their becoming the first paying customer. Nope.
