Django user proxy models fast access

Question

I have proxy model for user:

class MyUser(User):
    class Meta:
        proxy = True

How can i get it in templates without pass from view? can i get it only from request.user instance?

I am using template context processor for this:

def m_processor(request):
    from main.models import MyUser
    mu = MyUser.objects.get(id = request.user.id)
    return {'meuser':mu}

TEMPLATE_CONTEXT_PROCESSORS = (
    'settings.m_processor',
    )

Better solution exsists?
