> I try to find out if softflowd can read a pcap-'stream' from standard input? I know that softflowd can read from file with '-r file', but I need to read from a unix | (pipe) like tcpdump can do with 'tcpdump -r -'. Is it already possible today or is it easy to add it somewhere in the code?

Yes, it should be able to read from stdin using -r -, at least based on 
my understanding of the source [1] and function it calls ( 
pcap_open_offline [2] ).

Have your tried it; is it not working properly for you?
