[dev] user registration

[Marko]

i need to add a user registration to a few clients' site, so was thinking that
whilst i'm doing a hack for it i might as well do something valid which could be
contributed back as a patch.

this is what i thought of so far:
- have a simple form which would allow for user details to be submitted in two parts
    basic - which contains username/password and which could be stored in the
horde_users database.
    extra - which could contain any extra user definable info, like address,
email, notes, etc and i was thinking of using a modifed turba as a user/member
directory (linked to the actual username in the horde_users)
- to have admin validation this info could be submitted first as a serialized
string into horde_categories. once approved by admin it would be stored in the
respective tables
- as always backend drivers could be built to talk to each supported backend to
store the users, and if one is especially difficult, no point in holding back
doing the simpler ones like sql...

critical analysis of the above?
