[f-nsp] Outbound ACL Mirroring

Is it possible to mirror outbound / egress packets via ACL on an XMR  
with 5.1.00b?

I'm guessing not since I see no outbound ACL reference in the config  
guide and some quick testing in the lab yields unfavorable results.  
Thought I'd hit this mailing list in case I'm missing something simple.

For reference, this is not working:
!
interface ethernet 4/4
  ip access-group example_in in
  ip access-group example_out out
  acl-mirror-port ethernet 1/11
!
ip access-list extended example_in
  permit ip host 192.168.1.192 any mirror
  permit ip host 192.168.1.194 any mirror
  permit ip any any
!
ip access-list extended example_out
  permit ip any host 192.168.1.192 mirror
  permit ip any host 192.168.1.194 mirror
  permit ip any any
!

But there's traffic matching my mirror entries on the egress ACL:

telnet at name(config-if-e10000-4/4)#show acc account ethe 4/4 out

Outbound: ACL example
