Anyone know if this is supported/works:
!
pseudowire-class ATOM-E
  encapsulation mpls
  interworking ethernet
!
interface loopback0
  ip address 1.1.1.1 255.255.255.255
!
interface FastEthernet0/0.100
  no ip address
  encapsulation dot1q 100
  xconnect 1.1.1.1 50 pw-class ATOM-E
!
interface FastEthernet0/0.200
  no ip address
  encapsulation dot1q 200
  xconnect 1.1.1.1 50 pw-class ATOM-E
!

Basically creating a pseudowire across two subinterfaces on the same  
physical interface on the same router.
