[rt-users] customer view?

[rt at anothy.9srv.net]

does RT support different views for customers and admins? i'm
currently looking to deply it in a moderate-sized environment
(with an eye towards a large-sized one in the near future),
but it's a requirement that whatever we deploy be able to 
segregate users, such that user A can's see issues relating
to user B (assuming both are "external" users), but that all
"internal" users can see all issues.

this seems like it should be easy (from a DB point of view),
and is common in other systems, but i can't seem to fina any
mention of it.

i don't yet have a running rt system, but i'm working on an
install in another window this very moment.

any pointers, hints, or direct answers much appreciated.
