I believe I already know the answer to this, but thought I would ask anyway.
We are a school that takes pupils from 5 through to 19. Currently we are developing our Moodle installation for the secondary and sixth form students, and so our theme, log in process, etc. are all geared this way.
We would like to build in the ability to have the primary school section as well but their needs will be significantly different; with possible alternative log in options other than username and password, certainly a different theme, and (even with the same username and password log in routine) an alternative log in interface.
The obvious answer is a second installation of Moodle, but we would like it so that the work follows through with the student from year 0 through to year 13 (potato prints to chemical diagrams of the potato molecule!?! hahahaha).
