Note that libpcap 1.1 and later can read pcap-ng files as long as all interfaces whose packets are in the file have the same link-layer type and snapshot length (which will, obviously, always be the case if it was captured on only one interface).  Annotations are not seen by the application (and thus not written by libpcap-based programs), as the libpcap API doesn't currently provide a way to see them, but they won't prevent a libpcap-based program from reading a file with annotations.

...and, I think, packets that are included in reassemblies with the displayed packets, right?
