Can a non-root user create limited-rights processes without assistance

SELinux uses a restrictive model, where privileges can only be removed,
not added.
I think he was asking if a non-admin user can create processes of less
privilege without becoming root. The answer is yes, however, it is
policy driven. Users will have numerous 'derived' types that are less
privilege than, for example, their interactive shell. For example,
user_irc_t or user_evolution_t. The transitions will happen when the
user runs irc or evolution and those apps will be limited to the rights
they require. These are fine grained though, and mandatory. These
capabilities are so course grained I just can't see anyone ever using them.
