There are other file formats than include OID definitions including:
* ASN.1 modules/RFCs (e.g.
http://www.itu.int/ITU-T/asn1/database/itu-t/x/x420/1999/IPMSObjectIdentifiers.html)
* LDAP/X.500 directory schemas (e.g. http://www.faqs.org/rfcs/rfc2798.html)

It would be useful if that program could handle those as well. Would
the use of libsmi (which I know nothing about) limit this?

I have been using something like this in my private Wireshark for some
time. It allows me to add names to OIDs that Wireshark doesn't
natively know about, and also rename some of the in-built OID names.
I think it would be very useful to have this sort of functionality as
a mainstream feature.

Are you proposing a single file into which everything is compiled? In
which case will you program handle local, user-added, definitions
(e.g. not derived from a MIB).
