Re: About Dissector added with a "plugin" !

Not exactly what you are asking for    but you could try this:

(dissecting and displaying the top 12 bits of a 16 bit integer in a
somewhat binary representation)

{ &hf_foo,
{"Foo", "foo.foo", FT_UINT16, BASE_HEX, NULL, 0xfff0, "something", HFILL }},


I.e   specifying a bitmask which will make ethereal decode it and display it as
 XXXX XXXX XXXX ....


Probably not exactly what you want but maybe close enough?
