That will certainly give the user some context.
One thing I've found is that there is doesn't seem to consistent way
to name an OID. Having dumped all the names from the different
modules, there is a wide variance.
Do you think it would be worthwhile trying to describe how an OID
should be named in Ethereal? For example, should 2.2.1.0.1 be named:
"id-as-acse" - as defined in the standard
"acse" - (id-as if fairly superfluous)
"{joint-iso-itu-t(2) association-control(2) abstract-syntax(1)
apdus(0) version1(1)}" - to be complete
Personally I prefer the short form.

Interesting. I had looked at adding a new FT for OIDs as I wanted to
be able to add a menu item ("Field Info") to the packet info menu.
This would bring up a description of an OID - with the URL specified
as a preference (e.g. http://oid.elibel.tm.fr/2.2.1.0.1 or
http://www.alvestrand.no/objectid/2.2.1.0.1.html).
My inexperience with asn2eth put me off, so if someone else was to
implement an FT_OID ...

The plug-in still requires the ASN.1 to be wrapped in a TCP stream or
UDP packets and displays the ASN.1 differently to the specific
Ethereal dissector. For example, if I have a certificate in a file it
will not be dissected in the same was as a certificate in some CMS.
Also it requires you to do some compiling with SNACC.

OK.
