This code monkey-patches the default User model to rather use a primary key of UUIDField (see http://www.djangosnippets.org/snippets/1496/). This code also makes the email field required. This code is wildly dangerous, not completely future proof, and probably not advisable to use. If you do wish to use it, it will be easiest to implement on a fresh db with a syncdb. If you need to migrate existing user data the onus is on you to figure out an appropriate db migration plan.

I placed this code in a models.py, but it is probably more reliably placed in urls.py

if type(User._meta.pk) != type(UUIDField()):
    for f in User._meta.local_fields:
        if f.name == 'email':
            f.null = False
            f.blank = False
        if f.name == 'id':
            User._meta.local_fields.remove(f)
    User._meta.pk = None
    uuidfield = UUIDField(primary_key=True)
    User.add_to_class("id", uuidfield)
    temp = User._meta.local_fields.pop()
    User._meta.local_fields = [temp] + User._meta.local_fields
