Fascinating - I am looking forward to seeing this!

This seems arbitrary. Why 20?

Why not v3 as well? SNMPv1 is practically deprecated, so why bother
with v1? v2 is a nice middle ground - v3 is where everyone wishes to
be if they could start from scratch.

I'll be happy to figure out how this gets done. - Actually some quick
googling shows that the ASF already has an enterprise OID - and one of
our mentors has documented that here:
I will follow up with Alex and see if we can get an assignment.

So your idea here seems like it is targeting just sending traps, but
I'm far more interested long-term in being able to query the SNMP
daemon (and there likely will already be one on the host); so as you
are designing the MIB please do plan ahead for such things. The page
above is a good starting point around MIB design.

If you need help around this, I am happy to lend what little I know
about the subject of SNMP, or connect you with experts in the field.
