Ok I think the easiest thing for you to do now is change the range of 
the login user.

# semanage  user -m -r s0-s0:c0.c1023 guest_u
# semanage  login -m -r s0-s0:c0.c1023 __default__

(If you use a user other then __default__ you would need to change this 
also.)

I will send a patch to F11 to allow communications to fifo_files running 
at different levels.
