Got it, this could perhaps work and the downside would however be that the user wouldn't have complete control over the domain, unless DNS control is provided and before I can say the word, I'd be a domain name registrar.

I think it's cool idea though and I might give this a shot, thanks for the idea and if I do implement this then feel free to contact me through the form and I'll set "lifetime" account up for you!
