I had in mind to write a more generic command wrapper like:

$ pcapout --outfile=my.pcap curl http://kernel.org/

If pcapout would be such a wrapper programm, it could wrap the system calls of curl and generate a .pcap file without the need of root-right to listen on the network interface, as the system calls of curl and other programs provide enough information to build a correct .pcap file ( i think ). the program tsocks work in such a way. It wraps every socket-system call of the program and tunnels it through a socks tunnel. Writing such a wrapper would help more people than to write a patch for curl I think. I will try to work on this and post here if I have something worth showing.

Thanks
