I don't care for that solution much either. Assuming you had only 1 JV going on, it might not be a big deal...but what if you managed to set up 10 similar JV's with people like that on the same product? Now you have to set up 10 different versions of your sales page and all that.
I would assume that each would be a different product as far as the software was concerned, and therefore, you'd also have to compile your overall stats from each manually to figure out how things are going in a broader sense.
In addition, does JVManager work in cooperation with places like Clickbank? I don't recall it doing so, but then again, I usually have my own affiliate script built specific to whatever product is being released, so don't own all of the scripts out there.
Everything mentioned in this thread will do the job, however none of them are a solution to the overall problem. The problem is how to do those things in a simplified and secured manner that reduces the work needing to be done by the product owner and JV participant (i.e. automation), while still being completely accurate. Everything mentioned so far has just been a "workaround".
Sincerely,
Chris
