I will defer to Thomas's recommendations.

I don't recall the Intel PXE issue because I wasn't actively involved in the DHC WG at that time.

I think a better balance can be found. See my other note.

I disagree strongly with the idea that we give Cablelabs (or any
outside organization) a blank check to define options that extend DHC
without requiring any formal IETF/WG review. This can result in new
sub-options being defined that that don't make sense to us (i.e,
modify the protocol itself). Ditto on defining sub options that
duplicate existing options.

The IETF needs to review DHCP options to make sure they make sense and
are consistent with DHC. Remember the Intel PXE option? I recall folks
not being terribly happy about that.
