I'm toying with an idea here, but I'm not a programmer myself, so I'm not entirely sure whether it's possible, or even if it is, if it's legal too.

I would like to setup an online shop that sells, well, online shops. A user comes along, signs up and straight away get's an online shop. Rather than them having to pay for, and set-up their own merchant account, could all customer transactions go through one central account?

So basically, when a customer's shop sells something, the money is deposited in my account, before instantly and automatically being transferred to their own bank account?

Is this possible, legal and will the merchant's allow me to do this?

I'd be interested to hear any thoughts on the subject.
