Sounds cool  (I havent tested it yet)

I have some questions,
Will the plugin create and add new hf_fields to ethereal when it reads such
a spec file? So that all the fields it dissects
will have a proper filter name and blurb etc?  (so that all the fields CAN
be filtered?)

Would it be possible with this plugin to also generate etherealized
dissectors for the SNMP objects
described in the MIBS? (which do not have filterable fields :-( )

Could the plugin be used to decode any/all the other objects in other
protocols that are encoded as ASN.1 BER as well
(kerberos etc) so that all those protocols also get filterable fields?
