Define "materialize".  Wireshark is capable of reading and writing pcap-ng files, and has been capable of that for a while; libpcap 1.1.x can also read pcap-ng files that have only one link-layer type and snapshot length (because no API changes have been made to expose the additional capabilities).  Wireshark currently doesn't support the per-packet option fields, so it doesn't read the comments for the packet; if it were extended to support that, it could be used (although programs using libpcap to process packets wouldn't see the comments - and, unless they include their own pcap-ng code, they wouldn't be able to write out the files as pcap-ng files, so the comments and other options would be lost).
