User signup and domains?

[arpoodle]

I've had a trawl through the docs, and the forums, but can't see this mentioned anywhere, so either it doesn't exist or I'm being thick.

Is there anywhere for an end user to sign up themselves, or does a user always have to be created by an admin/reseller?

I'd like to have a "register" page where a new customer can sign up and create all their relevant domain/email info.

I recognise that this is of limited use unless domains are transferred in, or there's a mechanism to register domains from within the system, but for me there is a usecase for self registration.

On the subject of domains, there has been some talk about integration with ispcp and domain registration.

I use openSRS, and I believe they have an API/storefront.
Anyone know how difficult it would be to link the API into ISPCP and create domain registration facilities?
