There's no reason for not being able to do it. In fact, there's
little difference between "column.format" and other kinds of items, the
machinery already in place can handle changing it on the fly without any
modification, it only needs some minor bookkeeping in order to keep the
main copy in synch. I suppose that's proof of a well written piece of
code. :-)

My main motivation for delving into all this was actually to have
a tool more flexible than tcpdump for monitoring life traffic in the
console. Towards that end, having to fill in a list of titles and
formats for tethereal was only a minor annoyance. In the same vein, a
few cool text-only additions would be:
(1) a more flexible display format for %something formats, including
width fields and static text (right now static text seems to be
ignored in formats);
(2) color highlighting of the various fields, using curses;
(3) a way to display packet contents more terse than "-x", say
ASCII-only.
None of these should be excruciatingly hard to code.
