You can't do that right now because core_pattern doesn't support slashes. The coredumps will be always all over the fs or not be there at all if the cwd is write protected.
In my patch I allowed pipes and piped the coredump into a user space processor that generated a simple report using gdb and sent it off.
The web frontend then did some statistics on what crashed most.
