Hm, I'd love to hear more about the illegal thing you cited. My startup lets everyone choose, all we require is an EIN and there's no paperwork, and it's all been approved by my legal.

I've been through some various business types in the space, the worst was a registered Commercial Fundraiser where yes I had to setup bonds and the fees were ridiculous with individual filing between charity and state. But for you (and me actually) it doesn't seem as big of a deal until it hits scale. If you're referring to registrations for "Charitable Solicitation", we've been through that too. I quickly asked my legal and he responded with: as long as you're not specifically targeting persons in any state nor do you supply names and contact info for donors to the charities so they can't send thank you notes it's not an issue. YMMV and don't hold me to that, but it may not be a big issue for you and open up a new avenue.
