ssh.te already has an ifdef for nfs_home_dirs, which allows it to read
nfs_t:{dir file}.  We could probably make that a bit more generic and
have a /etc/security/selinux/home_dir_context which if it exists, is
used by any program that would otherwise use a specialized type.

Ok.

Maybe one solution would be to have a little SELinux daemon that the
kernel talks to over netlink to determine user identity.  This daemon
could then do things like talk to LDAP or whatever.
