Absolutely.  Unless you are talking about OAM being carried on a separate 
physical medium, arguments about side band vs frame based solutions seem to 
me to be somewhat spurious. The real issue here is whether the OAM traffic 
is bandwidth-limited or not.

Isn't option 3 just a specific example of option 2?
