Hmm not sure if I'm getting this right, do you mean white labelling Soul's authentication? To allow for rebranding?

yep, I'd like to offer your service @mydomain

That might be a possibility (it's not supported now though, we're still really really early stage) but I'm not opposed to that suggestion. This would work well if your network is pretty established already and folks trust your platform instead of trusting the authenticator first.

it's around 16,ooo (and growing thanks to the twitter kerfuffle) - very trusted in a small niche
