Pretty much if the "pdl" registers with the state as a CSO, they are totally unregulated as far as what they can charge for fees and such. They still would have to follow any interest rate caps, BUT they can charge a "fee", which is not considered interest, and there is no cap on the fee. Since there have been court cases that have found that these "fees" cannot be considered interest, they are safe to charge what they want. They do not have to be licensed.
So yes, if they are registered as a CSO the payday loan laws do not apply to them. You apply with the CSO, and the CSO, acting on your behalf, will get you a loan. They don't personally fund it, but they do service the loan. They would be the only company you would deal with.
This is how Cash Net USA is lending legally in Florida too.
