They'll likely put a rule in place that doesn't allow boosters and such to get involved. I think it'll end up being that a player can go work camps in the offseason and profit off that. For example: During the summer, Rondale is invited to work 5-6 WR camps where he is able to make a decent amount of money given his stature in the game right now. It benefits that individual running the camp while Rondale is able to use his ability to make some money for himself.
Also, this relates directly to the Manning QB Camp where college players typically have traded the ability to work with the Mannings and other QB guru's for working as counselors. Now, those guys can actually get paid. That's a better model.
It also will allow guys to use their likenesses to profit...especially in today's world of online social media. UCF's kicker lost his eligibility because he had an incredibly popular YouTube channel that he was profiting off of. With the way they are moving forward, the young man wouldn't lose that eligibility. (

If they do it in a targeted way, there will be little to no impact. However, you must also look at the benefit this provides for players in lesser sports like volleyball, soccer, tennis, etc. They can now work these camps and provide lessons where they are able to make money. It's a good thing...even for lesser sports.
