I don't think one can talk about packets in case of UNIX socket, there's simply
a data stream passing through the descriptor. I'd rather use strace/ltrace/truss
or similar tool to intercept read/write operations. 

It would be nice to have a tool that attaches to a given process and dumps all
data passing through a given descriptor in some nice format, though. It seems
feasible using PTRACE interface.
