Yes; you can ask pcap for the file descriptor which corresponds to your
sniffed device. That works at least on Unixes.
(There is also the 'any' pseudo-interface, if you are on Linux (and other
Unixes?). You get to listen /everywhere/ in one session.)

Modify pcapy so you can get the file descriptor from it. Pcapy is great, but
it doesn't expose libpcap literally. Maybe the original authors had no use
I've been meaning to write The Pcap Bindings To End All Pcap Bindings for
almost a year now, but I never seem to get around to it ;-)
