Ideally, yes.

Yes - that's pcap_findalldevs().

Yes.

Yes.  Join tcpdump-workers@xxxxxxxxxxx:

	http://www.tcpdump.org/#mailing-lists

(it's a fairly low-volume list) and ask about it there.  Give details of your new packet source, including the OSes on which it should be supported and the link-layer header type (if it's not one of the ones described at

	http://www.tcpdump.org/linktypes.html

you'll need a new link-layer header type value no matter *how* it's to be supported in Wireshark).
