Note that, as per the item added to your mail by the Ethereal mailing
list software, none of the former Ethereal core team are working on
Ethereal any more - they're all working on Wireshark.
As such, no new Ethereal releases have come out in a while, and no bug
fixing or new feature work has been done on Ethereal. That work is
being done on Wireshark.

Currently, two types of plugins can be written:
1) dissectors, which can only dissect packet data and add information
to the summary line and the packet details;
2) taps, which can process data handed to them by a dissector or can
process the raw protocol tree.
Dissectors are limited to extracting new protocol information from the
data. Taps could probably do the sort of processing you want.

See docs/README.tapping for some information on writing a tap.
See tap-protohierstat.c for an example of a tap that processes the raw
protocol tree.
See plugins/stats_tree for an example of a plugin tap.
