If so, is there any difference between it and the regular format other than the time stamp being seconds/nanoseconds rather than seconds/microseconds (e.g., extra fields in the file header or the per-packet header, or non-standard DLT_ values that collide with assigned DLT_ values)? Ulf might want to use that format as well.

Hi!
It's clear now that I'll need nanosecond resolution for the timestamps.
Guy, could you ask Dumas directly about the file format or hand me over his email address so I can ask him?
In the meantime I'll look at the changes needed in wiretap and elsewhere, so I'll get a working prototype soon.
