Hi, 

I apologize for the delayed response. Vacation interfered, and it looks
like I never answered this mail. 

1. You seem to agree with me that there may be a need to change the
common MIB module if new bonding schemes are defined. Building a more
modular scheme, possibly by defining IANA administered TC for
GBondSchemeList and GBondScheme could avoid at least part of the pain.
It's up to you and Benoit to decide if you want to do it now, or maybe
progress now the document as it is and deal with the issued later when
and if new bonding schemes appear. This is why I asked you how probable
this event is, I do not think that you answered). 

2. I can live with this explanation. 

Regards,

Dan
